Webb12 juni 2015 · b. Heat addition process of Rankine cycle is reversible isobaric whereas heat addition process of Carnot cycle is reversible isothermal. c. Heat addition process of Rankine cycle is reversible isentropic whereas heat addition process of Carnot cycle is reversible isothermal. d. both cycles are identical except the working fluid used. WebbA heat engine is a system which converts heat into work by taking heat from the reservoir ( hot body) to carry out some work. There is a discharge of some heat to the sink (cold body). In this system, there will also be some waste in the form of heat. There are different types of a heat engine in which a Carnot engine has the maximum efficiency.
Webb6 apr. 2024 · These are four processes in the Rankine cycle: Process 1–2: Isentropic compression: Working fluid is pumped from low to high pressure. Process 2–3: Isobaric heat addition: The high-pressure liquid enters a boiler where it is heated at constant pressure by an external heat source to become a dry saturated vapour.
