3-Steam enters the condenser of a steam power plant at a flow rate of 18000 kg /h, a degree of dryness of 0.86 and a pressure of 15 kPa, leaving the condenser as a saturated liquid at the same pressure. A nearby river water is used for the cooling of the condenser. Calculate the water flow rate of the cooler if the water of the river can be heated up to 10 ° C in order to avoid thermal pollution. (C_ (p, water) = 4.18 kJ / kgK) Note: the potential energy change is negligible.
