Note: In all of these problems, you can make the perfect-gas assumption, and take air o have =1.4 and R=287J/kgK 1. Plot the Fanno line for a flow with, at one point, pTsM=1.013105Pa=300K=6.867103kgKJ=0.25 Mark the following points on the curve: M=0.1M=0.2M=0.5M=1.0M=2.0M=5.0 Hint: Parameterize the Fanno line by Mach number, rather than by density. Set up a vector of Mach numbers, and use the static-to-sonic relations (and the Gibbs relation) to calculate h(M) and s(M)
