1. ### Basic Maxwell Speed Distribution Function

Homework Statement Homework Equations The Attempt at a Solution I DO NOT NEED HELP WRITING THE PROGRAM! I'm just trying to figure out the basics behind it. Since this is an integral I will be solving this problem by using riemann sums. Where I'm having the most trouble is in the...
2. ### Derive the energy equation for a van der Waal gas.

Homework Statement Derive the energy equation for a van der Waal gas when T and v are the independent variables. Homework Equations I'm required to start from: du=\frac{\partial u}{\partial T} dT +\frac{\partial u}{\partial v} dv The Attempt at a Solution We'll when I first...
3. ### Show that the Change in Volume is Independent of the Path

Ok thanks I'm going to take another look at what I did. Will post when I finish.
4. ### Show that the Change in Volume is Independent of the Path

Here is the work I have done so far. I did use the equations but I was having a hard time understanding in my mind the final values to plug in specifically for the final T value. I assumed it was referring to the final state so I plugged in 400 K. Please let me know if I made any mistakes...
5. ### Show that the Change in Volume is Independent of the Path

So would I have to change the equation of state around and plug it into each change of V, change of T, and change of P? Edit: I should plug them into the partial difference equation? The change in should be constants I think. Edit(again): The only equation I really have to plug in is V=(RT)/P...
6. ### Show that the Change in Volume is Independent of the Path

The equation of state would be PV=nRT. P- pressure V- volume n- number of moles T-temperature R-universal constant
7. ### Show that the Change in Volume is Independent of the Path

Homework Statement Homework Equations The Attempt at a Solution I understand what the question is asking. Both ways I should get the same answer. I'm having trouble figuring out the mathematics behind this question.
8. ### Fortran Fortran Help (Do Loop)

Hey guys, I'm new to fortran and I'm having a slight problem. I put my code below as reference. I first set up a my known values. Then I used an equation to solve for v. After I solve for v I then computed c which involves v. What I'm now trying to do is to loop the value I got for c back...
9. ### Two-conductor transmission line, find the potential difference V of th

Hey guys. I attached my work to this problem before but it didn't go through so here it is. It's ATTACHED. I also included so information from the textbook. if anyone has any ideas please let me know. Also I even asked my teacher and he said the answer I should be getting is the one that is...
10. ### Two-conductor transmission line, find the potential difference V of th

Two-conductor transmission line, find the potential difference V of the two conductors.? Two-conductor transmission line. At point P (x=43 cm, y=32 cm) in Fig. 2-10, |E|=450 V/m. If s=25 cm, h=29 cm, and r=12.5 cm, find the potential difference if these two conductors. Ans. =1.13 kV...

Ok I figured it out guys. Thanks to LCKurtz for explaining it to me. The function I had is correct -375r+300. Since it was a circle it was easier for me to put into circular coordinates. So I had to change from dxdy to r dr dΘ Whole set-up: ∫∫-375r+300 r dr dΘ from 0 to 0.8 then from 0...
