Q29. Steam enters the condenser of a power plant at 3 psia and a quality of 95% with a ratio ofmass flow of 40,000 lbm/hr. It will be cooled with water from a nearby river, which will circulate through the tubes inside the condenser. In order to avoid thermal pollution, the river water is not allowed to suffer from an increase in temperature.temperature greater than 18°F. If steam is to leave the condenser as a saturated liquid at 3 psia, determine how many times the mass flow rate of steam will be the mass flow rate of water, as well as the heat transfer from one system to the other.
