The 7fa gas turbine manufactured by general electric is reported to have an efficiency of 35.9 percent in the simplecycle mode and to produce 159 mw of net power. the pressure ratio is 14,7 and the turbine inlet temperature is 1288 0c. the mass flow rate through the turbine is 1,536,000 kg/h. taking the ambient conditions to be 300c and 100 kpa, determine the isentropic efficiencies of the turbine and the compressor. also, determine the thermal efficiency of this gas turbine if a regenerator with an effectiveness of 65 percent is added.
