If the overexpansion level of a Laval nozzle, run by a settling chamber at 5 atm and discharging to sea level atmosphere, is 36.1 percent, determine the design Mach number of the nozzle, treating the flow through the nozzle as adiabatic and reversible. A Mach 3 supersonic tunnel of test-section area 0.0025 m2 is run with stagnation state of 15 atm and 320 K. Determine (a) the power required to start the tunnel, and (b) the running power required.
