A gas turbine operates with air entering the compressor at 25oC and 1 bar. Compression carried out with a pressure ratio of 12. Exit gas temperature combustion chamber is 1000oC. The gas exits the combustion chamber then expanded in a gas turbine up to 1 bar. turbine and compressor works isentropic. Air enters at a flow rate of 250 moles/second. The working fluid used is compressed air considered an ideal gas with Cp/Cv = 1.41. Cp of air = 29 J/mol.K. a. Calculate the incoming heat b. Calculate the net work produced by the gas turbine c. Calculate the efficiency of the gas turbine
