##### Fresh water can be produced from saltwater by evaporation and subsequent condensation. An example is shown in Fig. $\mathrm{P} 10.42$ where $150-\mathrm{kg} / \mathrm{s}$ saltwater, state $1,$ comes from the condenser in a large power plant. The water is throttled to the saturated pressure in the flash evaporator, and the vapor, state $2,$ is then condensed by cooling with sea water. As the evaporation takes place below atmospheric pressure, pumps must bring the liquid water flows back up to $P_
