A blowdown wind tunnel exits to atmospheric pressure. In the working section where the cross-sectional area is 0.04 m2 , the flow has a Mach number of 3 and a pressure of 0.3 × 105 P a.
(a) What is the minimum stagnation pressure required?
(b) What is the minimum stagnation temperature required to avoid air condensation in the working section (the condensation temperature under these conditions is about 70°K)?
(c) What is the corresponding stagnation density under these conditions?
(d) What is the mass flow rate under these conditions?
