An adiabatic turbine operates at steady state. Air enters the turbine at a pressure and temperature of 800 kPa and 1100 K, respectively, and exits at 100 kPa. A temperature sensor at the turbine exit indicates that the exit air temperature is 700 K. Kinetic and potential energy effects are negligible, and the air can be treated as an ideal gas. Determine if the exit temperature reading can be correct. If yes, determine the turbine isentropic efficiency.

In a reheat-cycle power plant, steam enters the high-pressure turbine at 5 MPa, 450°C, and expands to 0.5 MPa, after which it is reheated to 450°C. The steam is then expanded through the low-pressure turbine to 7.5 kPa. Liquid water (Vi 0.001 m/kg) leaves the condensor at 30°C, is pumped to 5 MPa, and returned to the steam generator. Each turbine is adiabatic, with an isentropic efficiency of 81.6 % and the pump efficiency is 848 %. If the total...
