Air at 1.3 bar, 500 k and a velocity of 40 m/s enters a nozzle operating at steady state and expands adiabatically to the exit, where the pressure is 0.85 bar and velocity is 250 m/s. for air modeled as an ideal gas with k = 1.4, determine for the nozzle: (a) the temperature at the exit, in k, and (b) the percent isentropic nozzle efficiency.
