Air at 150Pa and 310K enters a compressor of inlet diameter 2cm. The Compressor raises the pressure to 3.5 times the inlet pressure and has an outlet diameter of 5cm. Determine the exit temperature and power input required, if the mass flow rate of air is 100kg/hr.

Final Temp T2
We know that
T1 / T2 = (P2/P1)^(K-1)/K
Where k = 1.4 for air as adiabatic process.

T2= (310)/ (3.5P1/P1)^(1.4-1)/1.4
...

#### Solution Summary
