3. 12 kg of air per minute is delivered by a centrifugal air compressor. The inlet and outlet conditions of air are: V1 = 12 , P1 = 100 KPa , vi = 0.5- and kg V2 = 90 , P2 = 800 KPa , v2 = 0.14 . The increase in enthalpy of air passing m kg through the compressor is 150 and heat loss to the surroundings is 700; KJ min" kg Find the work in Kw.
