A Method to Accurately Measure System Volumes for

Cooling towers or closed loop systems require continuous treatment. But to achieve effective water treatment in either of these settings, the precise system volume must be known. This is particularly essential when adding biocides to ensure the correct amount of treatment is added. Although there are many ways to measure volumes, many are inexact and hard to execute.

How to Calculate Volume Flow Rate | Sciencing

First, calculate the volume of water in the tank, remembering that the radius is half the diameter: π × (2.5 m) 2 × 3 m = 58.9 m 3. Then, determine the number of seconds in an hour: 60 s/min × 60 min/hr = 3600 s. Determine the required volume flow rate: Q = 58.9 m 3 / 3600 s = 0.01636 m 3 /s.
