QUESTION:
Nitrogen enters a steady-flow heat exchanger at , , and , and it receives heat in the amount of as it flows through it. Nitrogen leaves the heat exchanger at with a velocity of . Determine the Mach number of the nitrogen at the inlet and the exit of the heat exchanger.
ANSWER:
Step 1 of 4
Nitrogen flows through a heat exchanger. The inlet temperature, pressure, and velocity and the exit pressure and velocity are specified.
The Mach number is to be determined at the inlet and exit of the heat exchanger.
Assumptions are
1. 
2. This is a steady-flow process.
3. The potential energy change is negligible.
The gas constant of
