An insulated steam turbine receives 30 kg of steam per second at 3 MPa, 350 C. At the point in the turbine where the pressure reaches 0.5 MPa, steam is bled off for a feed heater at the rate of 5 kg/s. The temperature of this bleed steam is 200 C. The balance of the steam leaves the turbine at 15 kPa, 90% quality. Assume the environment is sea water at 0.1 MPa, 25 C.

(a). Determine the availability per kilogram of the steam at the point where the steam enters the turbine and at both points at which steam leaves the turbine.

(b). Sketch the process on an h-s diagram, labeling all states.
