(marks) 6) Prove that the following relationship is true for an isentropic process. T2 = T: Y-1 , Where P1.71 are the pressure and temperature at stage 1 and P2,72 are the pressure and temperature at stage 2 of the isentropic process. y is the ratio of specific heat at constant pressure (Cp) and constant volume (C) (c) Air is expanded isentropically in a nozzle from 13.8 bar and 150°C to a pressure of 6.9 bar. The inlet velocity to the nozzle is very small and the process occurs under steady conditions. Calculate the exit velocity from the nozzle if it is laid in a horizontal plane and the inlet velocity is 10 m/s. For air y = 1.4. (10 marks)
