Steam flows steadily through an adiabatic turbine. The inlet conditions of the steam are 4MPa. 500 degree Celsius and 80m/s and the exit conditions are 30kPa, 92 percent quality and 50m/s. the mass flow rate of the steam is 12kg/s. determine the change in kinetic energy, the power output and the turbine inlet area
