A steady stream of air enters a horizontal compressor at the rate of 0.02 kg/s. The air temperature is 10o C at entry and 300o C at exit. The velocity of the air is 30 m/s at entry and 6 m/s at exit. During its passage through the compressor, the air experiences a heat loss of 105 kJ/kg of air. Calculate: (a) The change in kinetic energy per kg of air (b) The change in enthalpy per kg of air (c) The work done per kg of air

Question
A steady stream of air enters a horizontal compressor at the rate of 0.02 kg/s. The air
temperature is 10o C at entry and 300o C at exit. The velocity of the air is 30 m/s at entry and
6 m/s at exit. During its passage through the compressor, the air experiences a heat loss of 105
kJ/kg of air. Calculate:
(a) The change in kinetic energy per kg of air
(b) The change in enthalpy per kg of air
(c) The work done per kg of air
(d) The power required to drive the compressor
(e) The volume of air entering the compressor per second
(f) The flow area of the entry pipe if the entry pressure is 1 bar
Take R = 0.287 kJ/kgK and cp = 1.005 kJ/kgK
