The ideal efficiency of simple gas turbine cycle principally depends on

Hot combustion gases (assumed to have the properties of air at room temperature, Cp=1.005 kJ/kg-K) enter a gas turbine at 0.8 MPa and 1500 K at a rate of 2.1 kg/s, and exit at 0.1 MPa and 800 K. If heat is lost from the turbine to the surroundings at a rate of 150 kJ/s, the power output of the gas turbine isQuestion 10Select one:a.(a) 1477 kWb.(b) 1677 kWc.(c) 1327 kWd.(d) 1124 kWe.(e) 872 kWf.Insufficient information to answer question
