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 variable specific heat, using values from Cengel's tables posted on Canvas. a) Find the exit velocity of the air (answer: 577.1 m/s). b) Find the isentropic efficiency of the nozzle (answer: 0.643).
