1. The problem statement, all variables and given/known data
I need to plot the Rayleigh line for a flow that has the following conditions at one point
(Perfect gass assumption holds, R=287 J/kgK, gama=1.4)
p = 101.3 kPa
T = 300 K
s = 6.867*10^3 J/kgK
M = .25
My question is what equation am I actually supposed to plot for a Rayleigh line?
Any help is appreciated. TIA
2. Relevant equations
change in entropy seen here as S_R

3. The attempt at a solution
So far i have tried plotting the change in entropy as a function of mach number but that does not seem to be right (seen here as S_R http://upload.wikimedia.org/math/7/0/e/70eca7a87051faef8ba16009e8f46fe2.png)
