As shown in figure 4, a combined gas turbine power plant operates with state 5 being an air compressor inlet at a temperature of 300 K and state 3 being a steam turbine inlet with a temperature of 1500 K. The pressure ratio of the gas-turbine cycle is 16. The isentropic efficiency of the compressor and turbine are 80% and 85% respectively. Air flow in the system with mass flow rate of 10 kg/s and the with turbine outlet temperature of 400 °C. The heat exchanger operates at 12 MPa and the combustion gas exit at 420 K. Steam leaves the condenser at 19.947 kPa. If the pump efficiency is 90%, Complete the table below: All to one decimal place except the Pr, s and x to 4 decimal places. If there are no numbers to write on decimal, replace the value with zero.
