A compressor receives air at 101.3 kPa at a steady rate of 0.5 kg/s and delivers at 700 kPa. At the inlet, the velocity and specific volume of air are 6 m/s and 0.83 m³/kg, respectively and those at the exit are 4 m/s and 0.15 m/kg, respectively. The internal energy of compressed air is greater than that of inlet air by 90 kJ/kg. Heat is removed from the cylinder at a rate of 60 W by the circulating cooling water. Determine the power required to drive the compressor.

Question
Transcribed Image Text:A compressor receives air at 101.3 kPa at a steady rate of 0.5 kg/s and delivers at
700 kPa. At the inlet, the velocity and specific volume of air are 6 m/s and 0.83 m³/kg,
respectively and those at the exit are 4 m/s and 0.15 m/kg, respectively. The internal
energy of compressed air is greater than that of inlet air by 90 kJ/kg. Heat is removed
from the cylinder at a rate of 60 W by the circulating cooling water. Determine the power
required to drive the compressor.
