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

11.2

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.
