QUESTION:
Air enters a compressor with a stagnation pressure of and a stagnation temperature of , and it is compressed to a stagnation pressure of . Assuming the compression process to be isentropic, determine the power input to the compressor for a mass flow rate of .
ANSWER:
Step 1 of 3
The inlet stagnation temperature and pressure and the exit stagnation pressure of air flowing through a compressor are specified. The power input to the compressor is to be determined.
It is assumed that
1. The compressor is isentropic.
2. Air is an ideal gas.
