Air enters a steady-flow turbine. The conditions of the airentering and leaving the
turbine are as follows: inlet, 300 kPa and 52°C; exit, 100 kPaand 12°C. The mass
flow rate is 10 kg/s. Heat transfer from the turbine to thesurroundings and the
kinetic and potential energy effects are negligible. Calculatethe power developed
by the turbine. Determine whether the process in the turbine isreversible. If not,
determine the isentropic efficiency of the turbine.
