Question 3.3 When the air with a pressure of 0.1 MPa and a specific volume of 0.8 m³/kg was provided into a compressor at a flow rate of 0.25 kg/s, its pressure became 0.7 MPa and its specific volume became 0.2 m³/kg. Through the compression, the specific internal energy was increased by 80 kJ/kg, and there was heat loss of 50 kJ/s to the environment. In this case, calculate the work [k]/s = kW] that the compressor did in unit time. Potential energy and kinetic energy can be negligible.
