Combustion gases enter an adiabatic gas turbine at 800oC and 900 kPa and leave at 100 kPa with a low velocity. Treating the combustion gases as air (R = 0.2870 kPa*m3/kg, cp = 1.005 kJ/kg*K, k = 1.4) and assuming an isentropic efficiency of 82 percent, determine the work output of the turbine and the exit temperature.
