15 kg of air per minute is delivered by a centrifugal compressor. The
inlet and outlet conditions of air are :
C1 = 10 m/s, p1 = 1 bar, v1 = 0.5 m3/kg and C2 = 80 m/s, p2 = 7 bar,
v2 = 0.15 m3/kg. The increase in enthalpy of air passing through the
compressor is 160 kJ/kg, and heat loss to the surroundings is 720
kJ/min.
Assuming that inlet and discharge lines are at the same level, find :
(i) Motor power required to drive the compressor.
(ii) Ratio of inlet to outlet pipe diameter.
