A combined power plant has a net power of 10 MW. Air enters the compressor at 100 kPa, 300 k, and compressed to 1200 KPa. The isentropic efficiency of compressor is 84%. Turbine inlet temperature and pressure are 1400 k, 1200 kPa respectively. Hot gases expand through the turbine which has an isentropic efficiency of 88% to a pressure .of 100 KPa If the heating value of fuel is 42400 ,kJ/kg.k and thermal efficiency is 49.55% Specific fuel consumption (sfc) in kg/kw.hr is a. 0.171 kg/kw.hr b. 0.373 kg/kw.hr c. 0.67 kg/kw.hr d. 0.145 kg/kw.hr اختر أحد الخيارات A combined power plant has a net power of 10 MW.
