Question
15 kg/min air is compressed. The inlet and outlet conditions are:
v1 = 10 m/s, P1 = 1 bar, V1 = 0.5 m3/kg
v2 = 80 m/s, P2 = 7 bar, V2 = 0.15 m3/kg.
 
The change in enthalpy is 160 kJ/kg, and heat exchange is -720 kJ/min.
 
If the inlet and discharge lines are at the same level, determine W in kW and the ratio of inlet to outlet pipe diameter respectively.
a. 28.8kW, 2.83
b. 28.8kW, 5.16
c. 52.8kW, 5.16
d. 52.8kW, 2.83
