P2) Steam flows steadily through an adiabatic turbine in a power
plant. The inlet conditions of the steam are 6 MPa, 400 °C and 119
cm2 . The exit conditions are 40 kPa, 92 percent quality, 50 m/s
and 20 kg/s. Determine the power output.

Steam enters an adiabatic turbine at 7 MPa, 700 °C and
80 m/s and leaves at 50 kPa, 150 °C, and 140 m/s. If the power
output of the turbine is 6 MW, determine:
