In a gas turbine plant, air enters the compressor at ambient conditions of 100 kPa and 25°C with a low velocity and exits at 1 MPa and 382°C with a velocity of 80 m/s. The compressor is cooled at a rate of 1500 kJ/min, and the power input to the compressor is 230 kW. (i) Identify the enthalpy of air (units: kJ/kg) at the compressor inlet, (ii) Identify the enthalpy of air (units: kJ/kg) at the compressor exit, and (iii) Determine the mass flow rate of air (units: kg/s) through the compressor.
