a) What does OTEC mean? What is the expected thermal efficiency of an OTEC system? b) An open-system OTEC plant operates with a surface water temperature of 30°C and a deep water temperature of 10°C. The evaporator pressure is 3 kPa and condenser pressure is 1.5 kPa. The mass flow rate of warm surface water entering the evaporator is 100 kg/s and the turbine has an isentropic efficiency of 85 percent. Determine (a) the mass and volume flow rates of steam at the turbine inlet, (b) the turbine power output and the thermal efficiency of the plant, and (c) the mass flow rate of the cold deep water. Neglect pumping power and other internal or auxiliary power consumptions in the plant.
