2021-10-28 · Falling film evaporator. First, we apply a differential mass (or mole balance) to both the gas side and the liquid side of the evaporator: which states that the change in the nuer of moles on the liquid side must show up on the gas side (or vice-versa). This results directly from conservation of total mass.
