8. A binary-vapour cycle operates on to the mercury turbine, from which it exhaust at 0.04 bar. The mercury condenser generates saturated steam at 15 bar which is expanded in a steam turbine to 0.04 bar. (1) Find the overall efficiency of the cycle. (i) If 50000 kg/h of steam flows through the steam turbine, what is the flow through the mereury and steam. mercury vapour at 4.5 supplied turbine ? (ii) Assuming that all processes are reversible, what is the useful work done in the binary vapour eycle for the specified steam flow? (iv) If the steam leaving the mercury condenser is superheated to a temperature of 300°C in a super- heater located in the mercury boiler, and if the internal efficiencies of the mercury and steam tur- bines are 0.85 and 0.87 respectively, ealeulate the overall efficiency of the eycle. The properties of saturated mercury are given below :
