1. The problem statement, all variables and given/known data I have been given a description of a thermodynamic cycle that looks like this. I have two polytropic processes (n1=1.2, n2=1.9), and one isochoric. The known data are: p1 = 1 bar T1 = 15 °C p2 = 15 bar 2. Relevant equations p v^(1.2) = 0.7958 p v^(1.9) = 0.69657 3. The attempt at a solution As you can see I've been able to compute the necessary values for the cycle in P-v. My interest is to now compute the values in T-s. I have all the temperatures, and using software I was able to compute the entropy for all points. My question is, how can I plot the data on the T-s diagram. For example, to plot the polytropes all I did was p = 0.7958 v^(-1.2) and it shows as a graph. My interest is now how to plot the polytrope in the T-s diagram, or at least how can I approach this problem?
