Question

The 7FA gas turbine manufactured by General Electric is reported to have an efficiency of 35. 9 percent in the simple cycle mode and to produce 159 MW of net power. The pressure ratio is 14. 7 and the turbine inlet temperature is 1288°C. The mass flow rate through the turbine is 1,536,000 kg/h. Taking the ambient conditions to be 30°C 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 66 percent is added. Use variable specific heats for air
