3. (25 Pts) Steam flows steadily through an adiabatic turbine. The inlet conditions of the steam are 6MPA, 400°C, and 80 m/s, and the exit conditions are 40 kPa, 92

percent quality, and 50 m/s. The mass flow rate of the steam is 20 kg/s. Determine (a) the change in kinetic energy, (b)the power output, and (c) the turbine inlet area.
