When we add a regenerator, cycle efficiency always increases. Time left 0:4 O a true O b. false In the following T-s diagram of Rankine cycle, process (1-2) is heat addition in boiler, process (2-3) is an expansion at turbine, process (3-4) is a condensation process and process (4-1) is a pumping process at feed pump. What is the formula for efficiency of Rankine cycle? Heat addition Pumping T A Expansion 4 3 Heat Rejection →S T-s Diagram of Vapour Power Cycle Select one: OnRankine = ((h2 - 93) + (hi-ha))/(12-hi) OnRankine = ((112 - 13) - (hi - ha))/(h2 - hi) OnRankine = (h2 - h3)/(h2 - h)) none of the above
The Brayton cycle consists of O a. two reversible isotherms and two reversible isochores O b. two reversible isobars and two reversible adiabatics O c. two reversible isotherms and two reversible isobars O d. two reversible isochores and two reversible adiabatics How can regeneration be used to improve the efficiency of Brayton cycle? O a. the energy of exhaust gas can be used to heat up the air which leaves the compressor O b. heat supplied from external source thus decreases O c. the amount of heat rejected also decreases O d. all of the mentioned
