 Air
enters a heat exchanger, operating at steady state, at 1 MPa and
600 K at a mass flow rate of 1000 kg/min. Heat is transferred to the air
at a rate of 4000 kW. Nitrogen, flowing separately, enters at 150 kPa and
800 K and leave at 120 kPa and 600 K. (a) Determine the exit temperature
of air, and (b) the mass flow rate of nitrogen. Neglect any change in kinetic
energy and heat transfer.
What-If Scenario: How do the answers change if the heat transfer has to be augmented to 5000 kg/min? Solution: Step-by-step instructions as well as the TEST-Code can be found in the Tutorial>Daemons>Open&Steady>Practice page. An image of the Analysis Panel is shown below. |
