Air at 101 kPa, 21oC, enters a compressor with negligible velocity and is discharged at 344 kPa, 330C through a pipe with a 0.09 m2 area, A2. The flow rate is 9 kg/s. The power input to the compressor is 447 kW. Determine the rate of heat transfer. Type your answer to 3 significant figures in units of kW. Do not type the units with the answer and quote your answer as a decimal value, i.e. 1234 not 1.234 x 10-3. Remember to include a minus sign if your answer is negative. The gas constant for air can be taken to be 0.287 kJ/kg-K. The specific heat capacity, cp, for air can be taken to be 1.005 kJ/kg-K
