A stream of oxygen enters a compressor at 25 \deg C and 1 bar with an inlet volumetric flow of 1.3 m^3/s and exits at 630 kPa. The compressor has an isentropic efficiency of 78%. It is estimated that the compressor loses heat to its surroundings at a rate of 3 kW at a temperature of 20 \deg C. Determine: a) The power required by the compressor b) The speed of entropy generation c) The velocity of exergy destroyed Consider T0 = 20 \deg C
