Derive an expression for efficiency of the Rankine cycle? How this cycle is different from the Carnot cycle? The Rankine cycle is the ideal cycle for vapor power plants. The ideal Rankine cycle does not have any internal irreversibility. Thermodynamic analysis of cycle : Process (4‐1): Constant pressure heat addition in a boiler. Process (1‐2): Isentropic expansion in a … [Read more...] about Efficiency of Rankine cycle
