Please update the following information as it applies to your tower needs: Gallons Per Minute. I just need to formula for rate of cooling. Have you calculated or estimated this? Liquid cooling, also commonly called water cooling, is the best solution for rapid heat removal due to its unmatched thermal performance. Rate of evaporation is approximately 1% of the circulation flow for each 10 °F (5.56 °C) of rise between the outlet and inlet across the tower. Now lets look at how to calculate the cooling capacity of a chiller in imperial units. 2. 1.14. To calculate water volume, some of the old “rules of thumb” such as five times recirculation rate just are not accurate enough for most applications. This calculator is set up using standard cooling tower calculations and rules-of-thumb.

It defines the fraction of total surface area of coil which is wet due to moisture condensation. Newton’s Law of Cooling states that the rate of change of temperature of an object is proportional to the temperature difference between it and the surrounding medium; using Tambient for the ambient temperature, the law is „Tê„t=-KHT-TambientL, where T is temperature, t is time, and K is a constant related to efficiency of heat transfer. 1.13 .
