Steam flows steadily through an uninsulated turbine. The inlet conditions of the steam are 6 MPa, 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. If the heat lost to the surroundings amounts to 10% of the power output, determine (A) the change in kinetic energy, (B) the power output, and (C) the turbine inlet area.
