A certain nozzle is designed to expand air from stagnation conditions of 1.38 MPa
and 200◦C to 0.138 MPa. The mass rate of flow is designed to be 4.5 kg/s. Suppose
this nozzle is used in conjunction with a blowdown wind-tunnel facility so that the
nozzle is suddenly allowed to discharge into a perfectly evacuated tank. What will the
temperature of the air in the tank be when the pressure in the tank equals 0.138 MPa?
Assume that the tank is perfectly insulated and that air behaves as a perfect gas.
Assume that the expansion in the nozzle is isentropic
