low to high pressure by a pump. Pumping requires a power input (for example mechanical or electrical). • Process 2 s-3: The high pressure liquid enters a boiler where it is heated at con-stant pressure by an external heat source to become a saturated vapor. Common heat sources for power plant systems are coal, natural gas, or nuclear power.
