Enter the total width of the waterfall (ft) into the Waterfall Flow Rate Calculator. The calculator will evaluate the Waterfall Flow Rate. 

Waterfall Flow Rate Formula

The following two example problems outline the steps and information needed to calculate the Waterfall Flow Rate.

WFR = W * 30

  • Where WFR is the Waterfall Flow Rate (GPM)
  • W is the total width of the waterfall (ft) 

How to Calculate Waterfall Flow Rate?

The following example problems outline how to calculate Waterfall Flow Rate.

Example Problem #1:

  1. First, determine the total width of the waterfall (ft). 
    • The total width of the waterfall (ft) is given as: 4.
  2. Finally, calculate the Waterfall Flow Rate using the equation above: 

WFR = W * 30

The values provided above are inserted into the equation below and computed.

WFR = 4 * 30 = 120 (GPM)

Example Problem #2: 

For this problem, the variables required are provided below:

total width of the waterfall (ft) = 6

Test your knowledge using the equation and check your answer with the calculator..

WFR = W * 30 = ?
