Q8: Two engine inlets, one a straight tube, the other a converging-diverging diffuser. Both with M = 2.0 at their inlets, T = 300.K, pi = 0.50 atm. Both slow flow down to same Me. The CD diffuser %3D flow is isentropically and straight diffuser with shock. Compare performance of diffusers of Me, Te, Pe, poe/po.
