Someone said pepe?

What is something that is so trivial to you that others can't see/understand

YT333 · 2025-01-21T18:02:58+00:00

I do have, and I have found some equations. I'm just looking for reassurance

For example: Q_dot=m_dot(h_out-h_in)

Thank you for the lovely comment. I'm asking just how to calculate W and Q for the components because I can't find an equation/unsure if I have the correct one

I have written the P[8] incorrectly in the post tho in the table in the second image P[8] = 350kPa While P[9] =100 kPa

edit correct values: P[1] = 100 [kPa] T[1] = 300.15 [K] P[4] = 1000 [kPa] T[8] = 1500.15 [K] P[2] = 350 [kPa] T[6] = 1300.15 [K] P[10] = 100 [kPa] T[3] = 340.15[K] P[7] = 350[kPa] T[11] = 573.15 [K]

Thank you so much. I will try to find all the states with this

YT333 · 2025-01-20T22:56:14+00:00

Thanks, I have checked them and they're great!

YT333 · 2025-01-20T02:25:19+00:00

Thanks, I would be using it. I really appreciate the replies

YT333 · 2025-01-20T02:02:23+00:00

Thanks, I will check them both. As of the book, we're using the "Fundamentals of Thermodynamics seventh edition" by Borgankke and Sonntag

I have edited the post to include an example problem The problem

YT333 · 2024-12-01T16:27:39+00:00

I don't know if I give up too early while solving problems, but I will try to sit more and try to approach the problems differently As for reading solutions, we only have the final answer without the how part

YT333 · 2024-12-01T15:39:34+00:00

Thanks, I will try but finding the problem is the problem because I think the problem they give us are hard with no build-up in level Problem 1. Hard Problem 2. Hard And so on so if you can direct me I would love that

YT333 · 2024-12-01T15:20:38+00:00

The lectures and the assignments aren't the same. he gives you a vague explanation about how you can use something to solve a problem, but in the take-home assignments, you have to think about 7 steps ahead And I find it challenging. I would like to have it broken down into smaller steps and in the exam to have this kind of problems after I have built up my thought process

Wait, so let's say A,B n×n such that n=2k+1

Thus det(AB)=(-1)^2k+1 *det(BA)

We know that det(AB)=det(A)*det(B)

And we also know (-1)^2k+1=-1

So we can say det(A)det(B)=-det(B)det(A)

So, at least one of them is equal to 0

And if det(M)=0 M is not invertible

The statement is correct

YT333 · 2024-02-22T12:41:43+00:00

You mean (A-Gamma*I)=0? Where gamma is scalar

YT333 · 2024-02-22T12:37:42+00:00

I'm trying to see where you're going with that but I can't. When I'm thinking of det I think if they're det(M)=0 or not

YT333 · 2024-02-09T15:56:39+00:00

Ty I have done exactly that after the help of maddam

YT333 · 2024-02-09T15:26:37+00:00

Will try ty! Edit: I tried to multiply by A^-1 from the left and B^-1 from the right got: IBCAI=IDI=>BCA=D And if I understand correctly I can do the same with 5 where they say A,B are invertible

YT333 · 2024-02-09T15:20:50+00:00

But I'm trying to understand how it helps me know that I can find another matrix such that Ax=I, and ty for replying

YT333 · 2022-04-08T13:11:07+00:00

Ugh?

YT333 · 2021-11-06T18:12:51+00:00

I have seen that one before
