Air enters an adiabatic nozzle at 230 kPa, 600°C with a velocity of 60 m/s. The air is at 70 kPa, 450°C at the exit of the nozzle. Model the air as an ideal gas having constant specific heats, using 300 K values from Cengel's tables posted on Canvas. a) Find the exit velocity of the air (answer: 552.4 m/s). b) Find the isentropic efficiency of the nozzle (answer: 0.599).
