- It Is Possible To Construct A Rankine Cycle Power Plant Using Warm Water Near The Ocean S Surface As A Heat Source And C 1 (51.16 KiB) Viewed 24 times
It is possible to construct a Rankine-cycle power plant using warm water near the ocean's surface as a heat source and cold water from the ocean's depth as a heat sink. For a particular plant operating with this configuration, the working substance is ammonia, the surface water is 80°F, and the cold water is 40°F. The ammonia is a saturated vapor entering the turbine and is 3°F less than the seawater temperature entering the heat exchanger and 3°F more than the seawater temperature leaving the turbine. The cycle is to produce 50 MW of power. Determine (a) the cycle thermal efficiency; (b) the cycle efficiency when considering the power requirements of pumps to move the seawater, which amount to 15 MW.
