Air enters a compressor with a mass flow rate of 1.25 kg/s at 105 kPa and 27oC and exits at 675 kPa and a specific volume of 0.1575 m3/kg. The work required to drive the compressor is 200 kW. The heat lost in this process is absorbed by an insulated water jacket where the temperature rises to 294 K from an initial value of 282 K with no change in pressure. Any heat loss from the water jacket may be ignored and all kinetic and potential energy changes are negligible. Determine the mass flow of the cooling water in the water jacket.
