Will a rankine cycle have efficiency equal to the carnot cycle, if the mean temperature of heat addition in rankine cycle is equal to the source temperature of Carnot cycle, and the mean temperature of heat rejection is equal to the sink temperature of carnot cycle.(adsbygoogle = window.adsbygoogle || []).push({});

My understanding is that in rankine cycle during heat addition, the working fluid temperature keeps on increasing at a constant pressure, where as heat is added from a source at a constant temperature. Hence the heat transfer occurs at a finite temperature difference, Thus the rankine cycle is internally reversible but not completely reverible. And its efficiency will be lesser than carnot efficiency.
