Two streams of air, one at 1 bar, 27degree and velocity of 30 m/s and the other at 5 bar, 227 degree and 50 m/s velocity, mix in equal proportion in a chamber from which heat at the rate of 100 kJ/kg is removed. The mixture is then passed through an adiabatic nozzle. Find the velocity of the stream issuing out of the nozzle. The temperature of air leaving the nozzle is 27degree, and its Cp=1.005kj/kg.K
