A cоnvergent-divergent nоzzle is designed tо operаte аt а Mach number of 2.3. The nozzle is supplied with air stored in a reservoir at a pressure of 3.5 MPa and a stagnation temperature of 300 K. The nozzle has a throat area of 25 cm2. Calculate the following: The mass flow rate through the nozzle under design conditions If the air supplying the nozzle was heated (stagnation temperature is increased), the mass flow rate (circle one) A. increases B. decreases C. stays the same The exit area of the nozzle The lowest back pressure for which there is only subsonic flow in the nozzle The back pressure required for the flow emanating from the nozzle to be ideally-expanded The back pressure that will make a normal shock sit at the exit plane of the nozzle The range of back pressures over which oblique shocks will occur in the exit flow The exit velocity if the nozzle exhausts into ambient air (pb = 101 kPa) The back pressure at which a shock appears at an area of 35 cm2 in the nozzle The Mach number at the nozzle exit for that condition
