Abinary vapor cycle consists of two rankine cycles with steam and ammonia as the working fluids. in the steam cycle, superheated vapor enters the turbine at 900 lbf/in.2, 1100°f, and saturated liquid exits the condenser at 140°f. the heat rejected from the steam cycle is provided to the ammonia cycle, producing saturated vapor at 120°f, which enters the ammonia turbine. saturated liquid leaves the ammonia condenser at 75°f. each turbine has an isentropic efficiency of 90% and the pumps operate isentropically. the net power output of the binary cycle is 7 x 107btu/h.(a) determine the quality at the exit of each turbine, the mass flow rate of each working fluid, in lb/h, and the overall thermal efficiency of the binary cycle.(b) compare the binary cycle performance to that of a single rankine cycle using water as the working fluid and condensing at 75°f. the turbine inlet state, isentropic turbine efficiency, and net power output all remain the same
