Cooling Tower Makeup Water Calculation with Example

Evaporation loss is loss of water due to evaporation. It is calculated by this equation: Evaporation loss = 0.00085 Wc (T1-T2) Where: T 1 – T 2 = inlet water temperature minus outlet water temperature ( oF) 0.00085 is evaporation constant (rule of thumb). The actual evaporation rate is a function of season and climate.
