Question: Nitrogen enters a steady-flow heat exchanger at 150 kPa, 10C, and 100 m/s, and it receives heat in the amount of 120 kJ/kg as it

Nitrogen enters a steady-flow heat exchanger at 150 kPa, 10°C, and 100 m/s, and it receives heat in the amount of 120 kJ/kg as it flows through it. Nitrogen leaves the heat exchanger at 100 kPa with a velocity of 200 m/s. Determine the Mach number of the nitrogen at the inlet and the exit of the heat exchanger.
