    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.
