Problem 5.52
Air is compressed from and to a pressure of while being cooled at a rate of by circulating water through the compressor casing. The volume flow rate of the air at the inlet conditions is , and the power input to the compressor is . Determine (a) the mass flow rate of the air and (b) the temperature at the compressor exit.
ANSWER:
Step 1 of 8
Air is compressed by a compressor. The mass flow rate of air through the compressor and the exit temperature of air are to be determined.
We will assume that
1. This is a steady-flow process since there is no change with time.
2. Kinetic and potential energy changes are negligible.
3. Air is an ideal gas with variable specific heats.
