The following design data is required to select cooling towers:
- Flow Rate in GPM
- Range of cooling in °F (T1 – T2)
- Area Wet Bulb Temperature in °F (Twb)
The Design Heat Load is determined by the Flow Rate, and the Range of cooling, and is calculated using the following formula:
Heat Load (BTU/Hr) = GPM X 500 X ° Range of cooling
If the Heat Load, and one of the other two factors are known (either the GPM or the ° Range of cooling) the other can be calculated using this formula.
- GPM = Heat Load (BTU/Hr) / 500 X ° Range of cooling
- ° Range of cooling = Heat Load (BTU/Hr) / 500 X GPM
The Design GPM and the ° Range of cooling are directly proportional to the Heat Load.
