The liquid is pressurized by the pump prior to going back to the boiler. Schematic of the Rankine Cycle : All four components associated with the ideal Rankine cycle are steady-flow devices, and thus all four processes that make up the Rankine cycle can be analyzed as steady-flow process. The kinetic and potential energy changes of water are
The calculation for cycles of concentration is: Cycles = Concentration of dissolved solids in the boiler water Concentration of solids in the boiler feedwater The above calculation assumes that all dissolved (ionized) solids in the feedwater remain dissolved in the boiler water.

cycle is the boiler/superheater. All of the heat input is at the boiler/superheater. The energy balance gives QH = (H3 – H6) = 3281.2 kJ/kg. The thermal efficiency is If we neglected the pump work, the efficiency would 29.23%. Note that the pump work has only a small effect on the thermal efficiency but is included for theoretical rigor. c.
