## 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:

- First, determine the total width of the waterfall (ft).
- The total width of the waterfall (ft) is given as: 4.

- 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** = ?**
