Brackish water is desalinated by evaporation for irrigation purposes. If the feed water has 800.96 ppm of salt, and if the product has to contain 0.0034 % salts as illustrated in Fig 1, what fraction of the feed water should bypass the evaporator?
feed water = 800.96 ppm
product water = 0.0034% = 34 ppm
part needed to bypass = =
