Transcribed Image Text:8. A binary-vapour cycle operates on mercury and steam. Saturated mercury vapour at 4.5 bar is supplied
to the mereury 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.
() Find the overall efficiency of the cycle.
GD If 50000 kgh of steam flows through the steam turbine, what is the flow through the mereury
turbine ?
(ii) Assuming that all processes are reversible, what is the useful work done in the binary vapour cycle
for the specified steam flow ?
(ie) If the steam leaving the mercury condenser is superheated to a temperature of 300°C in a super-
heater located in the mereury boiler, and if the internal efficiencies of the mercury and steam tur-
bines are 0.85 and 0.87 respectively, caleulate the overall efficieney of the eycle. The properties of
saturated mereury are given below :
