The air is compressed in a compressor. Before compression, the pressure and specific volume of air are P1=0.1MPA and v1=0.844 m3/kg. After compression, the pressure iss P2=0.8MPA and the specific volume is v2=0.174 m3/kg. It is known that after compressing 1kg of air during the compression process, the internal energy is increased by 140KJ; meanwhile, 56 kJ of heat is rejected to surroundings. The compressor produces 10 kg of compressed air per minutes. determine:
