Question: A closed-return wind tunnel with a large contraction ratio has air at standard conditions of temperature and pressure in the settling chamber upstream of the contraction to the working section. Assuming isentropic compressible flow in the tunnel, estimate the speed in the working section where the Mach number is 0.75. Take the ratio of specific heats for air as γ =1.4.
