Separate streams of air and water flow through the compressor and
heat exchanger arrangement shown in the figure below, where m,
0.6 kg/s and To = 30°C. Steady-state operating data are provided on
the figure. Heat transfer with the surroundings can be neglected, as
can all kinetic and potential energy effects. The air is modeled as an
ideal gas.
