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