Heat-Transfer Coefficient in Single-Effect Evaporator. A feed of 4535 kg/h of a2.0 wt % salt solution at 311 K enters continuously a single-effect evaporator andis being concentrated to 3.0%. The evaporation is at atmospheric pressure andthe area of the evaporator is 69.7 m². Saturated steam at 383.2 K is supplied forheating. Since the solution is dilute, it can be assumed to have the same boilingpoint as water. The heat capacity of the feed can be taken as c, = 4.10 kJ/kg · K.Calculate the amounts of vapor and liquid product and the overall heat-transfercoefficient U.

Given that, The mass flow rate of the feed F = 4535 kg/h The weight fraction of salt in the feed xF…
