# CALCULATION TIPS FOR COOLING TOWERS

**Sizing a Cooling Tower**

**To determine the estimated capacity of any Cooling Tower System, it is recommended to use Liquid Molybdenum or similar trace product and follow the formula below:**

**Pounds of trace product added x 120,000 x percent active ÷ parts per million of chemical trace increase**

**To determine the volume of a Cooling Tower Sump:**

**Length x Width x Height x 7.5 = Water Volume of the Sump**

**To determine the volume of a Chilled Water Loop:**

**The GPM of the recirculating pump ÷ by 3 = tonnage of the ChillerTonnage of the Chiller x 20 = System Volume**
