Water enters a condenser at a pressure of 200 kPA and a quality of 0.95. The pressure drops by 25 kPa across the condenser as heat is extracted to a 30C thermal reservoir. If the water exits as a saturate liquid,
determine :
a) the change in specific entropy of the water,
b) the change in specific entropy of the reservoir, and
c) the entropy production per unit mass of the entire process.
