for example, a cooling tower sized to cool 4540 m 3/hr through a 13.9°c range might be larger than a cooling tower to cool 4540 m3/hr through 19.5°c range. range range is determined not by the cooling tower, but by the process it is serving. the range at the exchanger is determined entirely by the heat load and the water circulation rate through the

### Cooling Tower Makeup Water Calculation With Example

recall again, cooling tower makeup water = evaporation loss + drift loss + blowdown. let’s calculate each component. evaporation loss = 0.00085 x 10 000 x (100-85) = 127.5 gpm; drift loss = 0.02% x 10 000 = 2 gpm; blowdown = [127.5 – (5-1) x 2]/(5-1) = 29.87 gpm; cooling tower makeup water = 127.5 + 2 +29.87 = 159.37 gpm; reference:
