Transcribed Image Text: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 1200 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.
(b) the percent isentropic turbine efficiency.
