Determining the Exit Temperature and Power Input of Air through a Compressor

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.

...T2 = 310/ (3.5)^(0.4)/1.4 K

Power Required:
m = mass of air = 100/60*60 kg/sec

(h1 + v1^2 /2) + w = (h2 + v2^2/2)
We need to know ...
