Superheated steam from the boiler expands in the turbine from inlet pressure p₁ of 50 bar and temperature 7 of 487 °C to condenser pressure p2 of 18 kPa. In the condenser, the steam condenses to saturated water. The isentropic efficiency of the turbine ns is 78.0 %. The mass flow of steam 9m,h is 140 kg/s. In the boiler, heat flow rate to the circulating fluid (water/steam) is 458 MW. Read from h,s-diagram and calculate: 1. Enthalpy of the superheated steam h kJ/kg (with zero decimal accuracy) 2.

A binary-vapour cycle operates on mercury and steam. Saturated mercury vapour at 4.5 bar is suppliedto the mercury turbine, from which it exhaust at 0.04 bar. The mercury condenser generates saturatedsteam at 15 bar which is expanded in a steam turbine to 0.04 bar.(i) Find the overall efficiency of the cycle.(ii) If 50000 kg/h of steam flows through the steam turbine, what is the flow through the mercuryturbine ?(iii) Assuming that all processes are reversible, what is the useful work done in the binary vapour cyclefor the specified steam flow ?(iv) If the steam leaving the mercury condenser is superheated to a temperature of 300°C in a superheaterlocated in the mercury boiler, and if the internal efficiencies of the mercury and steam turbinesare 0.85 and 0.87 respectively, calculate the overall efficiency of the cycle. The properties ofsaturatedmercury are given below :
In a steam plant 100 kg/min of dry-saturated steam at 30 bar enters the turbine. After expanding isentropic ally the exhaust steam enters the condenser. The condenser pressure is maintained at 0.1 bar by the cooling water taken from a nearby river. Calculate the following: a. Dryness fraction of exhaust steam. b. Turbine work output. c. Work input to the feed pump. d. Heat supplied to the boiler. e. Heat rejected to the cooling water. f. Efficiency of the plant. g. Net power output.
