E = Q/1000 = (T1-T2) / 1000 x L
E= Evaporating Water
Q= Heat Load
1000 = Water Evaporation Heat
T1= Inlet Water Temperature
T2= Outlet Water Temperature
L= Circulating Water Flow

The Loss Of Carry-Over
The loss of Carry-over depends on the cooling tower design, and Air Velocity. Generally
speaking, the loss is equal to 0.2% to 0.3% of total circulation water.
11.3
The Loss of Regular Blow-Down
To decrease the loss of blow-down, please follow the procedures below:
A. Open the drain on the hot water basin while the cooling tower is in operation.
B. Increase the operational water level to anticipate the water flowing out of the overflow outlet
C. Replace the water in the cold water basin and pipes annually.
The water quality and its concentration of solids will determine the loss of regular blow-down.
Generally speaking, the loss is about 0.3% of total circulating water.
11.4
Make-up Water Calculation
The total make-up water of circulating water is equal to:
M = E + C + D
M = Make-up Water
C = Carry-over
When the cooling tower is rigged to an air-conditioner, the cooling range is set at 10
case, the make -up water needed for the cooling tower is about 2% of the circulation water.
