A simple ideal Brayton cycle operates with air with minimum and maximum temperatures of 27°C and 877°C. It is designed so that the maximum cycle pressure is 2000 kPa and the minimum cycle pressure is 100 kPa. Determine the net work produced per unit mass of air each time this cycle is executed and the cycle's thermal efficiency. Use constant specific heats at room temperature. The properties of air at room temperature are cp=1.005 kJ/kg-K and k = 1.4. Compressor 0 Lout Lin Turbine (4) Wnet The net work produced per unit mass of air is The thermal efficiency is %. | kJ/kg.
