Steam steadily flows through a turbine to produce mechanical work. At the inlet, the pressure, temperature and velocity of the steam are 10 MPa, 450 °C and 110 m/s, respectively. The water exits this turbine at pressure of 10 kPa with the quality of 90% at velocity of 20 m/s. During this process, the rate of heat loss from the turbine to the surrounding air is 12 kW. The mass flow rate of the steam is 10 kg/s. Ignoring the changes in potential energy, determine: a) the change in specific kinetic energy, in kJ/kg b) power output of the turbine, in kW c) the area of the exit port of the turbine, in m^2?
