(6) In an open cycle gas turbine plant, air at 15°C and 1.013 bar is compressed through a pressure ratio 5:1. The maximum temperature in the cycle is 8000 0 C and gas expands 1 in two turbine stages to the original pressure, with reheating at constant pressure of 2.265 bar to 800 0 C between the stages. The air compressed in two stages, with complete intercooling, division being made for optimum conditions. The isentropic efficiencies of the compressors and turbines are 0.8 and 0.9 respectively. Determine (a) Power of mass flow of 20 kgs (b) Overall thermal efficiency. (c) Air-fuel ratio Assume cp= 1.005 throughout the cycle and calorific value of fuel = 41800kJ/kg.
