The throat area a convergent–divergent jet nozzle is 0.0125 m2 and the nozzle entry conditions for the flow are 2.0 MPa and 1500 k respectively. Assuming stagnation conditions at the entry, estimate the flow rate through the nozzle. The ratio of specific heats may be assumed as 1.37. The nozzle exit area = 0.1m2, inlet pressure and temperature are 2.5 MPa and 1100 k respectively. Exit pressure is 113745 Pa. The ratio of specific heats may be assumed as 1.4.

Convergent -Divergent nozzle
A∗A2=0.01250.1=8
From the isentropic flow tables we have γ=1.37;M=2.89
In this case divergent section of the nozzle acts as a nozzle
