Problem 4. A converging-diverging nozzle, a with throat area of A₁ = 10 cm², is attached to a large tank inwhich the pressure and temperature are maintained at po = 8.0 bar and To = 350 K. The nozzle exit area isA₁ = 14 cm². (a) For a throat Mach number of Mat = 1 determine the exit Mach number corresponding tothe following three cases: case I (isentropic subsonic flow, Mar), case II (isentropic supersonic or "designconditions" flow, Maд), and case III (flow with a normal shock in the exit plane, Maш). (b) Determine the backpressures corresponding to all three cases: PI, PII, and P. (c) Sketch the corresponding T-s diagram for all threecases. (d) Briefly discuss how changing the exit area changes the design Mach number.

The diameter of the duct is 10cm and the air temperature and pressure at the inlet are T₁ 450 K and P₁ = 200 kPa. If the Mach number at the exit is Ma2 determine the rate of heat transfer and the pressure difference across the duct. The constant pressure specific heat of air is cp = 1.005 kJ/kg-K.

For supersonic and hypersonic wind tunnels, a diffuser efficiency, ηD,can be defined as the ratio of the total pressures at the diffuser exit andnozzle reservoir, divided by the total pressure ratio across a normal shockat the test-section Mach number. This is a measure of the efficiency ofthe diffuser relative to normal shock pressure recovery. Consider asupersonic wind tunnel designed for a test-section Mach number of 3.0which exhausts directly to the atmosphere. The diffuser efficiency is 1.2.Calculate the minimum reservoir pressure necessary for running thetunnel.
