Power Plant Equipment

An open cycle gas turbine plant uses heavy oil. Max pressure=500 kPa, max temperature=650°C. Air at 10⁵ Pa, 27°C enters compressor. Isentropic efficiencies of compressor and turbine are 80% and 85%. Find thermal efficiency. If plant consumes 5 kg/s fuel, find power generating capacity. Take Cp=1 kJ/kg°C and γ=1.4.
