A gas turbine has an overall pressure ratio of 5 and a maximum cycle temperature of 550 celcius. The turbine drives the compressor and an electric generator, the mechanical efficiency of the drive being 97%. The embient temperature is 20 celcius and airs enter the compressor at rate of 15 kg/s, the isentropic efficiencies of the compressor and turbine are 80% and 83%. Neglecting changes in kinetic energy, the mass flow rate of fuel, and all pressure losses, calculate
a)the power output
b)the cycle efficiency
c)the work ratio
