Isentropic Flow Through Nozzle - GATE ME '11
The temperature and pressure of air in a large reservoir are 400 K and 3 bar respectively. A converging-diverging nozzle of exit area of 0.005 m2 is fitted to the wall of the reservoir as shown in the figure. The static pressure of air at the exit section for isentropic flow through the nozzle is 50 kPa. The characteristic gas constant and the ratio of specific heats of air are 0.287 kJ/kg.K and 1.4 respectively.
The density of air in kg/m3 at the nozzle exit is A. 0.560 B. 0.600 C. 0.727 D. 0.800
The mass flow rate of air through the nozzle in kg/s is A. 1.30 B. 1.77 C. 1.85 D. 2.06
