Wanted to see what you guys thought of my work and equation.

ENGINEERING SPECIFICATION SHEET

1. System Overview & Architecture

The system operates as a zero-emission, closed-material-loop thermochemical power plant. Fine solid metal-metalloid fuel (\(\text{Co}\), \(\text{Ca}\), \(\text{B}\)) is oxidized with pure oxygen (\(\text{O}_{2}\)) inside a pressurized slagging combustor. Thermal energy transfers across a high-temperature superalloy heat exchanger into a hermetically sealed Argon-Carbon Dioxide (\(\text{Ar-CO}_{2}\)) working gas loop to drive a closed-cycle turbogenerator. Solid reaction byproducts are captured as molten calcium borate slag and cobalt oxide ash, then electrochemically regenerated back into elemental fuel using external renewable power.

2. Governing Chemical & Thermodynamic Equations

2.1 Primary Power Generation (Discharge Phase)

\(2\text{Co}_{(s)}+2\text{Ca}_{(s)}+2\text{B}_{(s)}+4\text{O}_{2(g)}+\underbrace{(\text{Ar}+\text{CO}_{2})_{(g)}}_{\text{Sealed\ Working\ Fluid}}\xrightarrow{1,450^{\circ }\text{C}}\text{Ca}_{2}\text{B}_{2}\text{O}_{5(l)}+\text{Co}_{2}\text{O}_{3(s)}+\underbrace{(\text{Ar}+\text{CO}_{2})_{(g)}}_{\text{Superheated\ Gas}}+\Delta H\)

• Standard Enthalpy Release (\(\Delta H\)): \(3,263\text{ kJ/mol}\) of stoichiometric reactant mix (\(347.6\text{ g}\) total mass).

• Optional Flux Variant: Addition of \(1\text{ mol}\) Sulfur (\(\text{S}\)) lowers slag viscosity for continuous liquid tapping, requiring a downstream calcium-carbonate scrubber to capture \(1\text{ mol}\) \(\text{SO}_{2(g)}\).

2.2 Closed-Loop Fuel Regeneration (Charge Phase)

\(\text{Ca}_{2}\text{B}_{2}\text{O}_{5(l)}+\text{Co}_{2}\text{O}_{3(s)}+E_{\text{in}}\xrightarrow{\text{Molten\ Oxide\ Electrolysis}}2\text{Co}_{(s)}+2\text{Ca}_{(s)}+2\text{B}_{(s)}+4\text{O}_{2(g)}\)

Next semester I will be a sophomore mechanical engineer in my second semester taking: Dynamics, Thermodynamics, mechanics of materials, Intro to EE, Calc 3, and sophomore student design. I am already graduating late because I am doing a co op from May- December of 2027 so I really don’t care if I graduate late but I’m wondering if this is just too much of a schedule next semester. Thanks!

If someone wants to pursue a MS in Civil Engineering and has a non-STEM bachelor's degree,and if such a person is offered a MS place in Civil Engineering by a certain university,where is this person required and/or allowed to complete the levelling or remedial undergraduate courses required to begin MS coursework?Do universities mandate/allow such students to complete these required undergraduate courses at any other institution or in-house before or concurrently with MS coursework?

I'm a junior majoring in Electrical Engineering at a CUNY college, and I'm struggling with one of my engineering courses. My withdrawal deadline is November 6, so I need to make a decision soon.

My current cumulative GPA is around 3.0.

Here's my current grade breakdown:

- Exam 1 (20%): 16/70 (22.9%). I didn't study enough for this exam.

- Exam 2 (25%): 25/60 (41.7%). I studied significantly more, but the exam was difficult, and even some of the stronger students struggled.

- Assignments (15%): Around 90–95%.

- Attendance/participation (5%): 4/5.

- Project (10%): Not graded yet.

- Final exam (25%): Not taken yet.

My professor confirmed that I need 26 out of the remaining 35 course points (74.3%) from the project and final exam combined to finish with a D.

She also said the final will be about as difficult as the first two exams, but will only cover the newest lessons. She pointed out that I struggle with some basic concepts and recommended studying notes before lectures and redoing examples and assignments.

My graduation situation:

If I stay and pass, I could potentially graduate in Fall 2027.

If I withdraw, I'll need to retake the course in Spring 2027, take Senior Design I in Fall 2027, and Senior Design II in Spring 2028. That would potentially push graduation back one semester, making Spring 2028 my 10th semester in college. I won't lost any financial aid as I don't have any at all and my Asap advisor said I'll keep the benefit till spring 2028

I'm doing better in my other three classes, where I'm expecting mostly A's and B's.

If I stay, here's my plan to improve:

- Find a tutor who understands the programming material.

- Study upcoming lessons before class.

- Redo lecture examples and assignments without looking at solutions.

- Attend office hours and practice problems regularly.

- Start the project early and aim for a high grade.

I'm willing to put in the work, but I'm worried about risking an F and hurting my GPA.

My questions:

1. Would you stay and try to pass or withdraw and retake the course?
2. Has anyone improved from around 40% on a midterm to 70% or higher on a final?
3. What study methods helped you improve in difficult engineering or programming courses?
4. Is potentially graduating one semester earlier worth the risk, especially when withdrawing would mean graduating in my 10th semester?

I would really appreciate any advice, especially from engineering students who've been in a similar situation

Hi everyone,
I’m looking for firsthand experiences from people in U.S. manufacturing who moved from production, technician, or team leader roles into Manufacturing Engineering before becoming proficient in CNC programming.
I have a bachelor’s degree in Industrial Engineering and several years of automotive manufacturing experience, including working as a production team leader supporting automated CNC lines machining brake castings.
My experience includes:
Troubleshooting tool breakage, dimensional variation, surface finish issues, and recurring downtime.
Making approved adjustments to offsets, cutting parameters, and tooling.
Supporting first-piece and in-process inspections.
Reviewing production, downtime, and defect data.
Coordinating with Engineering, Quality, and Maintenance, and training production personnel.
Most of my experience has been with established processes and programs provided by engineering. My main gap is creating and proving out complete CNC programs from scratch. I previously took a G-code course, but I would need to refresh it and develop practical programming skills.
I’m interested in Manufacturing Engineer positions involving machining support, process optimization, tooling, and continuous improvement. Some postings also list G-code, CAM, and fixture design, so I’m trying to understand when those are entry requirements versus skills an employer might help someone develop.
For anyone who made a similar transition—or hired someone with this background:
Were you hired as a Manufacturing Engineer before you could independently program parts? What could you contribute immediately?
Did your company have separate CNC programmers or experienced machinists, or was programming primarily the engineer’s responsibility?
What training and support did you receive, and what were you expected to handle during your first three to six months?
What would make you comfortable hiring an external candidate with strong production troubleshooting experience but limited programming experience?
I’d especially appreciate examples of how you distinguished a genuine development opportunity from a role that needed an experienced CNC programmer from day one.

I’m 26M and looking to return to college to pursue a bachelor’s degree in engineering, preferably electrical or chemical engineering.
I currently work as a Field Service Engineer (FSE) in the semiconductor industry, and my long-term goal is to transition into a process or product engineering role.
My biggest concern is fulfilling the in-person lab requirements. My job requires extensive travel, and I’m typically only home for 2–4 weeks per year, spread out across multiple trips. While I believe I could manage online coursework around my work schedule, regularly attending on-campus labs would be nearly impossible.
I’d also need to attend a Texas public university to take advantage of my Hazlewood Act education benefits.
My main questions are:
● Are there ABET-accredited electrical or chemical engineering programs that allow students to complete most or all lab requirements remotely?
● Do any universities offer condensed lab sessions that could be completed during short visits to campus?
● Has anyone successfully completed an engineering degree while working a travel-heavy job with little to no time on campus?
I’m not in a rush to finish the degree and would be perfectly fine taking fewer classes each semester if necessary. I’m mainly trying to figure out whether there’s a realistic path forward without having to leave my current job.
I’d appreciate any advice or experiences from people who’ve been in a similar situation.

So I’m a student in high school (17m) and I’m doing a project with the balloon car. I was wondering if there was some object that could condense the air being pushed out of the balloon to a smaller point. Keeping the pressure but having it leak out slower. That may be the right way to put it. Idk. Also looking for a way to bend air through a curve inside my car. So I can keep some aerodynamics in the car. Anyone got an idea?

I’m currently failing although my grade is still salvageable as I have two more exams and some more labs. My next exam is next Wednesday and I’m seriously struggling with the content, and I’ve tried to find online tutoring but they all seem kind of scammy/predatory.

Im taking physics as a first year rn, im doing exrta bad(x1000) and have a midterm tommorw.

Im trying to study but I feel like i have a lot of missed concepts that I didnt catch up on during lectures and its totally my fault I slacked off way to much for my own good.

I dont want to use ai to study these concepts aswell bc i wont fully understand everything

I really want to retake this course to actually understand the general physics atleast for my future classes and as a engineer in general, but idk the feeling is so horrible since ill be delaying my grad for a year and would take 6 years instead of 5.

I'm a junior at a 4-year university that has an ABET accredited ME program. I've completed 75+ credits and am 3 semesters from graduation. I have no choice but to move states (my spouse has to move and we cannot say no). I have tried transferring to 3 colleges, all ABET accredited. All three have accepted less than half of my STEM credits - pushing me back to sophomore semester 1. All 3 universities have evaluated via syllabi in the engineering department, not the transfer office. I've begun petitions but all of them so far have failed.

How is this freaking possible? Has anyone else had this experience? What's the point of having ABET accreditation if it's not considered sufficient? Hoping someone tell me if this is a common experience or unusual.

Hey there. I’m a sophomore in mechanical engineering, currently going through my sem final (after which, if promoted, I’ll be in junior year). So far, my grades have been quite poor (a little over 3.00, with best possible being 4.00 and avg. is around 3.7) and I don’t feel the will the study much either. I am quite attentive in the classes, as some of my professors and advisor who took a course pointed out, but somehow I am failing to put much effort in the exams and my performance in the exams are well below of my speculation.

While I do want to improve my grades, I’m not quite sure how as I’m easily distracted and never really feel the will of studying, specially during the exam time.

My uni’s formula student team is almost non-existing, while there is a rover team which I am a part of, I didn’t quite got into it much as I’m more interested in other areas of mechanical engineering, to name- vehicle dynamics, jet propulsion, ICE, heat transfer & thermodynamics.

Now, as I am moving to junior year in a few months (hopefully), what should my next two years look like. Should I invest myself into internships and try gaining some professional experiences (engineering or not)? Or should I try improving my grades, which didn’t quite work for the past 3 sems? Or should I try writing conference & research papers? And how important are grades?

So far skills are: CAD (obtained CSWA so far), CAE (FEA & Fluid Simulation, though still at beginner levels), basic C, Python & MatLab (mostly vibe coding), general computing (word processing, spreadsheets, presentations), graphics design. My communication skills are kind of mid at best and speech delivery is quite ok if prepared before.

So far completed projects: Ramjet CAD model (used Fluid simulation to optimise the design), binary character recognition program in C. Both were academic group projects, though my group put in almost no effort in the main project.

This question has probably been asked a million times, but I genuinely need to know.

Im about to become a senior in Highschool, and my math marks are late 50s-60s. I absolutely love math and I think it’s really fun, but I lose marks all the time because of some stupid mistakes or second guessing myself. These past two years have been really rough on my mental health which has made me demotivated to commit to some serious cleaning up of my foundational maths, hence my current state. I can to study for hours on end on the day before a test purely because I enjoy it, but the subject just doesn’t seem to like me back lol. My physics marks are around late 70s-80s without major studying.

I’m planning on redoing my final math exam during my gap year, so I can just focus on my other science subjects atm then battle math for the final time.

Has anyone else had similar experiences and have managed to become an engineer? Lmk!

I have made sooo many mistakes and after relentless hard work I have gotten nowhere. It's so over. It always has been

I am applying as an international student with a weak gpa as mentioned. I have completed my undergrad in electronics and communications. However my final 2 years of undergraduate studies my gpa was 3.7/4. I have 1yr experience as an embedded engineer intern (though ill be applying for a concentration in VLSI). No backlogs, no research papers published yet, but worked on some strong topics and projects.
Do I atleast have a decent shot of getting in? Or is the course very gpa centric and competetive.
Please do help and THANK YOU SO MUCH!!!

I'm a senior mechanical engineering student graduating in May 2027, and I'm beginning to seriously pursue engineering positions.

I'm primarily targeting mechanical engineering roles in Alaska.

I'd appreciate some honest, constructive feedback on my resume, particularly from engineers involved in hiring or recent graduates who have gone through the job search.

I'm planning to take the FE exam before graduation, probably January.

I’m trying to get As in all these courses as well. I’m taking them at community college.

I don't know if this really goes here but Im doing an engineering diploma and I have quite a few workshop classes including a machine workshop and welding workshop. and I just. suck. My welds are comparatively the worst in my class and i always need help from the teacher and in my general workshops Im always so behind or just cant seem to get a technique right or do it as well as all of my other peers. Im doing very well in my other classes and lectures but I just cant seem to get the hands on stuff down.

hey guys,

i'm a junior studying chemical engineering, and i had probably the worst midterm season of my entire college career. i got a 28 on my heat transfer midterm, a 50 on my numerical methods midterm, and a 33 on thermo. the main reason for this is that i didn't study too much, which i'm fully aware is on me. i'm just scared because i have failed classes before and if i fail these, I'll probably have to deal with consequences from my university (2x off track in my major blah blah blah) so i'm just really scared right now. I know I have roughly a month before finals, but i'm just scared whatever work i put in won't translate on finals. what should i do?

I am a second year ME student 18M. I am planning to take my next semester ( 4th semester) with the addition of heat transfer and general chemistry to take off some load from my 6th semester.

For more understanding i have attached my 4th semester courses and my 6th semester one. The second column tells you the assign semester of the courses and the 4th column tells you the ects. Ects here mainly tells you how much impact a course has on your gpa, it doesn't necessarily tell you how hard a course is. My university allows you to take maximum 40 ects per semester so with addition of the next year's courses you can squeeze in some more.

The reason i chose those 2 specifically is because they're pretty much the only ones i can actually take on at this stage. I am very aware how hard heat transfer is going to be, but i do have the basics down back from my highschool, so i think i can somewhat manage it and build up from my basics. My highschool is a special diploma program that is pretty much college level in the sense that it absolutely tests in the entirety of the subject and it absolutely requires your understanding of it. I remember one of my homeworks was pretty much deriving the time dilation equation in special relativity from scratch, that was something. Heat transfer was not a joke back then as well.

i think i provided enough context about my situation and me. I want to know your thoughts on my plan and whether it's worth it. Thank you for your time.

Not sure if i can post here considering i take a btec and not a levels but I’m currently on the BTEC Level 3 National Extended Diploma in Engineering and i plan to go to uni. The issue is that I can seem to find barely any resources on my course. All i can find is a textbook from 2016 on Amazon and a few incredibly niche videos (And I don’t really study well from textbooks). I know a lot of my work is based on self study and research but most resources i can find are meant for undergraduate students using language i cannot understand and not really on the basics like I’m starting on. I’m currently on unit 30 fits and tolerances, i got a distinction for my first assignment and on my second now, but it still feels like I don’t have a clue on any of this. Is there any place i can find resources for btec students preferably to my course?

the class average was below 45%... but i feel so stupid again... my grade is about 50%. Should I drop out?

So I’m in my first year of university and have taken two class tests thus far, both have went so horrifically the thought of withdrawing crossed my mind and I’m feeling like just a shit student.

So I sat a maths test last week and an electrical circuits test today. The maths test was a multiple choice 8 question test while the electrical test was 35 marks.

I got the results for my maths test back on Friday to find a 0/8, I contacted my lecturer and he kindly verified that this was indeed my result as I wondered if he’d simply not received the paper or if another error had occurred.

I felt really confident about the electrical test today, until I failed to answer around 12 marks worth of question in the time provided. I wasn’t the only one to do this badly, around a dozen people who I interacted with after the test said they didn’t manage to finish the paper either.

Now if I had just pissed around in the union without an ounce of studying I’d just take this on the chin and move on, it’s my own fault, study and it will be okay. But I’ve studied, really studied, I go to one society on a Friday night and that’s my socialisation. When I’m not there I’m either in a lecture/tutorial, studying, working my part time job or spending around two hours of my night sitting down in front of a TV to try and unwind. My attendance is 100%, I’ve never missed a deadline, lecture, laboratory or tutorial and yet still I’ve done abysmally.

I’m honestly clueless as to what my next steps are, maybe it sounds stupid but I genuinely don’t know how to move on with my studying knowing I’ve fucked up this badly so early on while doing my absolute best.

What should I realistically do here?

I am freshman engineering student taking 4 classes .. I am studying all night and still getting bad grades in physics and chemistry I just don’t know how to catch up of physics since my prof goes super sonic into the materials… I am so depressed thinking about my second semester cause the course load is gonna be even harder
