An ideal gas mixture with k = 1.31 and a molecular weight of 23 is supplied to a converging nozzle at p0 = 5 bar, t0 = 700 k, which discharges into a region where the pressure is 1 bar. the exit area is 50 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.
