two isothermals and two isentropics

two isentropics and two constant volumes

two isentropics, one constant volume and one constant pressure

carnot cycle can′t work with saturated steam

heat is supplied to water at temperature below the maximum temperature of the cycle

a rankine cycle receives heat at two places

rankine cycle is hypothetical

constant pressure

constant temperature

constant volume

constant entropy
