An adiabatic turbine has steam flowing steadily through it. The inlet conditions of the steam are P1=6 MPa, T1= 400C and v1=80 m/s, while the exit conditions are P2= 40kPa, .9 quality x=.9, and v0= 50 m/s. The mass flow rate of the steam is m= 20kg/s. Determine the change in kinetic energy, b the power output, and c the turbine inlet area.
