Air with a mass flow rate of 2.5 kg/s enters a horizontal nozzle operating at steady state at 480 K, 350 kPa, and velocity of 5 m/s. At the exit, the temperature is 300 K and the velocity is 450 m/s. Using the ideal gas EGMN 204 Spring 2020 model for air with constant cp = 1.011 kJ/kg · K, determine: (a) the area at the inlet, in m2 . (b) the heat transfer to the nozzle from its surroundings, in kW
