A gas-fired power plant operating on a Brayton cycle draws in 9.0 kg/s of atmospheric air, initially at 300 K and 100 kPa, in order to generate 1.7 MW of electricity. If the combustion chamber adds heat by burning 0.07 kg/s of fuel with a heating value of 46.1 MJ/kg, and as a result the air entering the turbine is at a temperature of 861 K, determine the back work ratio of this device to 2 decimal places. You may treat the added mass of the fuel as negligible. Take the cp of air to have a constant value of 1.005 kJ/(kg K) throughout the whole cycle, and its ratio of specific heats k can be assumed to take the value 1.4.
How are the combustion and exhaust processes modeled under the air-standard assumptions?
