A modified Brayton cycle is to be analyzed using the air-standard assumption with constant specific heats at a temperature of 300K. Air flows through the Brayton cycle with a mass flow rate of 400 kg/s and enters the first compressor with a pressure of 100kPa and a density of 1.2 kg/m3.It is then compressed to 800kPa in the first of two compressors with an isentropic efficiency of 85%. After this compression, the air is cooled at constant pressure where it is now found to have a volumetric flow rate of 57.4 m3/s when it enters the second compressor. The second compressor has an isentropic efficiency of 85% as well and the air leaves this stage of the cycle at a pressure of 2.5 MPa.The cycle has a regenerator with an effectiveness of 75% which heats the air to a temperature of 600K after leaving the final compressor. The air enters the first turbine which has an isentropic efficiency of 90% at a temperature of 1200K after which it expands to a pressure of 700 kPa. The second and last turbine stage has an isentropic efficiency of 80%.Determine:a) The temperature of the air leaving the last turbineb) The net power production of the cyclec) The thermal efficiency of the cycle
