The topping cycle is a gas-turbine cycle that has a pressure ratio of 8. Air enters the compressor at 300 K and the turbine at 1300 K. The isentropic efficiency of the compressor is 80%, and that of the gas turbine is 85%. The bottoming cycle is a simple Rankine cycle operating between the pressure limits of 7 MPa and 5 kPa. Steam is heated in a heat exchanger by the exhaust gases to a temperature of 500°C and the isentropic efficiency of the turbine is 90 %. The exhaust gases leave the heat exchanger at 450 K. Considering the mass flow rate steam as 1 kg/s, determine: A) Net power, B) Total input heat, C) Total entropy generation, D) Energy efficiency, E) Exergy efficiency, F) T-s diagram Solve by EES Compressor Air -③ in Exhaust gases Pump Combustion chamber Gas turbine Gas cycle Heat exchanger Condenser Steam Steam turbine cyclearrow_forwardI need expert solution s to this question, don't use Artificial intelligencearrow_forward

The natural gas consists primarily of CH4 with small quantities of several other light hydrocarbons and can be represented as C1.16H4.32 To achieve low emissions of oxides of nitrogen, the burner operates lean at equivalence ratio of 0.4. Assume complete combustion and answer the following questions. i) What is the operating air-fuel ratio (i.e. mass air/mass of fuel)? [6 marks] ii) What is the percent excess air in the combustion products? [3 marks] iii) What is the oxygen (O2) mole fraction in the combustion products? [6 marks]arrow_forward
