Air modeled as an ideal gas enters a turbine operating at steady state at 1040 K, 278 kPa and exits at 120 kPa. The mass flow rate is 5.5 kg/s, and the power developed is 800 kW. Stray heat transfer and kinetic and potential energy effects are negligible. Assuming k-1.4, determine (a) the temperature of the air at the turbine exit, in K.
