Question: A converging-diverging nozzle is designed to operate with an exit Mach number of 1.75. The nozzle is supplied from an air reservoir at 1000 psia. Assuming onedimensional flow, calculate
a. Maximum back-pressure to choke the nozzle
b. Range of back-pressures over which a normal shock will appear in the nozzle
c. Back-pressure for the nozzle to be perfectly expanded to the design Mach number
d. Range of back-pressures for supersonic flow at the nozzle exit plane.
