Calculations involving retention time involve the following formula, T =, where V is volume and Q is flow rate. Often times, you will be required to calculate the volume of more than one tank and determine a rate of flow, given a total retention time. Tank 1 Tank 2 Let's assume that the total retention time for the entire system is 55 minutes, and we want to know the inlet flow, given the dimensions of tank 1 are : 14m x 10m x 3 m, and tank 2 are: 5m x 10m x 3 m. Calculate the inlet flow.
