Acompressor (open steady system) operates between the following inlet and exit states: state-1 (inlet): h=141 kj/kg, s = 0.581 kj/kg. k; state-2 (exit): h= 172 kj/kg, s = 0.581 kj/kg. k. due to poor insulation, the compressor loses heat at a rate of 10 kw. the mass flow rate is 10 kg/s, and the surrounding temperature is 300 k. a) determine the compressor power (absolute value) in kw. b) determine the rate of entropy generation in the compressor's universe in kw/k
