Air with a mass flow rate of 2.3 kg/s enters a horizontal nozzle operating at steady state at 420 K, 350 kPa, and velocity of 11 m/s. At the exit, the temperature is 300 K and the velocity is 460 m/s. Using the ideal gas model for air with constant c, = 1.011 kJ/kg - K, determine: (a) the area at the inlet, in m?. (b) the heat transfer to the nozzle from its surroundings, in kW.

Question
Air with a mass flow rate of 2.3 kg/s enters a horizontal nozzle operating at steady state at 420 K, 350 kPa, and velocity of 11 m/s. At
the exit, the temperature is 300 K and the velocity is 460 m/s.
Using the ideal gas model for air with constant c, = 1.011 kJ/kg · K, determine:
(a) the area at the inlet, in m?.
(b) the heat transfer to the nozzle from its surroundings, in kW.
Part A
Determine the area at the inlet, in m2.
A1 = i
m2
