An ocean thermal energy conversion (OTEC) system is being proposed for electric power generation using a Rankine cycle with ammonia as the working fluid. The system is to be used in a location where the oceanic water temperature near the surface is approximately 20oC, while the temperature at a reasonable depth below the surface is approximately 15oC. Consider a power plant that is to generate 2 MW of electricity. For the specified conditions determine the:
(a) Maximum possible thermal efficiency for this cycle if the ammonia enters the turbine as a saturated vapor.
(b) Mass flow rate of ammonia through the system.
