Air is expanded isentropically in a nozzle from 13.8 bar to 150^@Cto a pressure of 6.9 bar. The inletvelocity to the nozzle is very small and the process occurs in steady state, steady flow conditions. The exist velocity from nozzle, when inlet velocity is 10 ms^(-1)is found to be k xx130 ms^(-1). Find thevalue of k, assuming nozzle is horizontal, also take C_p = 1.005.
