(a)
By writing an energy balance on the heat exchanger of a binary vapour power cycle, obtain a relation
for the exit enthalpy regarding the mass flow rates of two fluids in terms of the other enthalpies. Take the
topping cycle and bottoming cycle to enter the heat exchanger at states 1 and 3, respectively, with exit at
states 2 and 4, respectively. Use subscript 'A' for the topping cycle and 'B' for bottoming cycle. (b) State the
two assumptions considered for the expression.
What is the primary purpose of the binary power cycle?
Name two types and binary power cycles and describe them.
