Air with a mass flow rate of 2.3 kg/s enters a horizontal nozzle operating at steady state at 450 k, 350 kpa, and velocity of 3 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_p = 1.011 kj/kg*k, determine
(a) the area at the inlet, in m^2
(b) the heat transfer between the nozzle at its surroundings in kw.
(c) specify whether the heat transfer is to or from the air.
