Hydrogen is expanded isentropically in a nozzle area with an initial pressure of 600 kPa, with negligible velocity, to final pressure of 100 kPa. The initial gas temperature is 550K. Assume steady flow with hydrogen behaving as a perfect gas with CP= 14.5 kJ/Kg K. Determine the final gas velocity and the mass flow through the nozzle for an exit area of 500 x 10^4 m2 and R is 4.124 kJ/kg K.
