Air enters a compressor operating at steady state at 1 atm with a specific enthalpy of 290 kJ/kg and exits at a higher pressure with a specific enthalpy of 1023 kJ/kg. The mass flow rate is 0.1 kg/s. Kinetic and potential energy effects are negligible and the air can be modeled as an ideal gas. If the compressor power input is 77 kW, the rate of heat transfer between the air and its surroundings is 3.7 kW from the air to the surroundings. O 150.3 kW from the air to the surroundings. O 150.3 kW from the surroundings to the air. O 3.7 kW from the surroundings to the air.
