Question

Stack gases exhausting from electrical power plants are at approximately 150°C.Design a basic Rankine cycle that uses water, R-134a, or ammonia as the working fluid and that produces the maximum

amount of work from this energy source while rejecting heat to the ambient air at 40°C. You are to use a turbine whose efficiency is between 88 to 96 percent and whose exit quality cannot be less than 85. percent.
