Steam enters an adiabatic turbine at 500C and 4.0MPa and 80m/s. The steam leaves the turbine as saturated liquid-vapor mixture at 30kPa, quality of 92% and 50m/s. The mass flow rate of steam through the turbine is 12kg/s.
(10 pts) Determine change in kinetic energy
(10 pts) Determine the rate of work (power) done by the steam in the turbine, in kW (neglect potential energy change).
(10 pts) Determine the flow area at the entrance to the turbine, in m2. (Hint: use mass flow rate definition).
