Question

An ideal gas mixture with k 5 1.31 and a molecular weight of 23 is supplied to a converging nozzle at po 5 5 bar, To 5 700 K, which discharges into a region where the pressure is 1 bar. The exit area is 30 cm2. For steady isentropic flow through the nozzle, determine

(a) the exit temperature of the gas, in K.

(b) the exit velocity of the gas, in m/s.

(c) the mass flow rate, in kg/s.
