Two questions: 1. What does the T-s diagram look like for the irreversible cycle? 2. Do the isentropic efficiency equations that you apply to turbines and compressors (especially in the Rankine cycle) apply to the theoretical "turbines" and "pumps" in the Carnot cycle?

Homework Statement See the picture for the homework problem: http://i41.tinypic.com/2drk2x.png Homework Equations I'm having trouble converting between the first equation and the second one. I understand that Nu_x=h_x*x/k Re = rho*v*x/visc Pr = c_p*visc/k But how the heck do I...

Can I get some help with this? I don't even know where to begin.

Ok, quite the noob with MATLAB right now. I have heard of vectorize though! Thanks :cool:

Great! Got it working, thanks for the help!

Matrix "." Help in MATLAB Here is my code: f=linspace(0,1000,1000); xf=abs((1-exp(1-2*pi*f.*1i))/(2*pi*f.*1i-1)+(((exp(4*pi*f.*1i)-1)*exp(1-6*pi*f.*1i))/(2*pi*f.*1i))+(((2*pi*f.*1i-1)*exp(1-6*pi*f.*1i)+exp(1-10*1i*f.*pi))/(8*pi^2*f.^2*1i))); func=plot(f,xf) I just need to know where the...

Wow thanks so much for the helpful reply!

I have the following DE: y'=y*(1-y^2) And understand that y=0, and y=+/-1 are critical points I am confused as to which are stable/unstable and why. TIA

Ok that's what I was hoping - thank you.

Q is the amount of dye in the tank. dQ is the rate of change of the amount of dye in the tank.

Homework Statement Consider a tank used in certain hydrodynamic experiments. After one experiment the tank contains 200 liters of a dye solution with a concentration of 1 g/liter. To prepare for the next experiment, the tank is to be rinsed with fresh water flowing in at a rate of 2...

Ok so for question one I found out why I was getting R_eq = 9.9 instead of 9.6 and I've found it is because I have the international edition of the book and the resistor on the left is 4Omega instead of 5Omega - sneaky.
