5 A steady stream of air enters a horizontal compressor at the rate of 0.02 kuts. The air temperature is 10°C at entry and 300°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 between entry and exit (b) The change in specific enthalpy of the air between entry and exit (c) The work done per kg of air (d) The power required to drive the compressor (e) The flow area of the entry pipe if the entry pressure is 1 bar Take R=0.287 kJ/kgK and cn=1,005 kJ/kgK for the air. (Ans. -0.432 kJ/kg. 291.45 kJ/kg, -396,018 kJ/kg, 7.92036 kW, 541.47 mm)
