What did you get for the value of quality, x?
Once you have the value of x you can easily calculate almost anything you could want, let's say you want entropy, s1=sf + x1sfg
let's say you want internal energy, u1=uf + x1sfg
and so on, enthalpy, specific volume, etc. etc.
In terms of...
Integrate it over what, since your variables are m, c and T, is it dm, dc or dt? I know that formula but I don't actually have any experience using it other than I recall for some stuff in a physics course I took two semesters ago...and I'm 99% sure it's not super accurate because it uses...
I think it's my background, I currently work as a math tutor while I go to school and I find myself trying to find different ways to help students understand what's going on. Right now it's mostly high school kids so it's fairly simple math, but I've managed to help quite a few students that...
Hello! I certainly don't mind helping you, feel free to ask me anything thermo I, I truly loved the course and it challenged me at the same time. Generally speaking you're always going to want to sketch P-v (specific volume) or T-v (specific volume) graphs because specific volume is in your...
I've attached a picture that is essentially the setup for the problem. There's really only one other major obstacle to overcome and that is that the states are not fixed. I.e. state 1 all you know that is obvious is that P1=0.1Mpa=100kpa but you need to know something else to be able to start...
I think part of my difficulty is in deciding relavant parameters. Ultimately what I'm trying to do is accelerate air up to 56ms via a compressor and then a nozzle. Why not a propeller you might ask and a motor, well to be quite frank with you, I haven't yet had any course that introduces a...
Additional tips:
Anytime you start a problem classify it as an open or closed system (if you're unclear what I mean by this I can elaborate).
Then try to classify the type of process if possible based on the information given. For example, it could be an isobaric, isometric, isothermal...
I believe it depends on where you take it as well as the instructor but if you know all necessary mathematics and chemistry prerequisite information then you should be perfectly fine. I went into thermo I with just the prerequisites and I've never learned so much in one class before (except...
How? I thought the whole purpose of the absolute value stemmed back to distances along a number line, therefore you couldn't get a negative value out of the absolute value of a number or a function?
I came up with my own design problem, after completing a refrigeration design problem on the completion of my thermo I class. My design problem is this: I want to accelerate air to 56m/s via a compressor and then a nozzle. I'm trying to do a cost analysis of how much power I would save if the...
I think you're absolutely on the right track. I'm currently a mechanical engineering (BSME) student and my school also offers mechanical engineering technology. You can go to the website (ipfw.edu) and basically look through the two course programs and you'll immediately notice that mechanical...
Is there some way you could either scan and upload the figure or possible explain the figure in words? I don't have enough information and I'm genuinely interested in the problem and solution.
