SUMMARY
The discussion focuses on plotting the Fanno flow entropy equation in a temperature-entropy (T-s) plot, specifically the equation S2-S1=R*(M2-1)*log(T2/T1). Participants clarify the need to determine whether to plot S2-S1 against T2 or T2/T1. The Mach number (M) is identified as a variable dependent on both temperature (T) and entropy (S), necessitating a contour plot for accurate representation. The brute force method for generating a contour plot involves creating a grid of S and T points to visualize the relationship defined by the equation.
