Igure P4.95 shows a turbine operating at a steady state that provides power to an air compressor and an electric generator. Air enters the turbine with a mass flow rate of 5.4 kg/s at 5278C and exits the turbine at 1078C, 1 bar. The turbine provides power at a rate of 900 kW to the compressor and at a rate of 1400 kW to the generator. Air can be modeled as an ideal gas, and kinetic and potential energy
changes are negligible. Determine (a) the volumetric flow
rate of the air at the turbine exit, in m3/s, and (b) the rate of
heat transfer between the turbine and its surroundings, in kW
