A combined gassteam power plant has a net power output of MW The pressure ratio of the gasturbine cycle is : Air enters the compressor at bar & K while leaves the combustion chamber at K The combustion gases leaving the gas turbine are used to heat the steam at MPa. to deg C in a heat exchanger. The combustion gases leave the heat exchanger at K If the fuel used in the combustion chamber is octane CHis which is supplied at deg C and burned completely with excess air. An open feedwater heater incorporated with the steam cycle operates at a pressure of MPa. If the condenser pressure is kPa. and all the compression & expansion processes are isentropic sketch the combined cycle and the corresponding Ts diagram, then determine:a the mass flow rate ratio of air to steam,b the required rate of heat input in the combustion chamber,c fuelair ratio,d combustion gases specific heat, C and dew point temperature,
