Required information NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. Air at 620 kPa and 500 K enters an adiabatic nozzle that has an inlet-to-exit area ratio of 2:1 with a velocity of 120 m/s and leaves with a velocity of 380 m/s. The enthalpy of air at the inlet temperature of 500 K is h = 503.02 kJ/kg Determine the exit pressure of the air. The exit pressure of the air is -652.73 kPa.
