Enter the pipe fall (ft) and the pipe length (ft) into the Pipe Slope Calculator. The calculator will evaluate and display the Pipe Slope.

## Pipe Slope Formula

The following formula is used to calculate the Pipe Slope.

PS = PF / PL * 100

- Where PS is the Pipe Slope (%)
- PF is the pipe fall (ft)
- PL is the pipe length (ft)

To calculate a pipe slope, divide the pipe fall by the pipe length of the same units.

## How to Calculate Pipe Slope?

The following example problems outline how to calculate Pipe Slope.

Example Problem #1:

- First, determine the pipe fall (ft).
- The pipe fall (ft) is given as: 25.

- Next, determine the pipe length (ft).
- The pipe length (ft) is provided as: 97.

- Finally, calculate the Pipe Slope using the equation above:

PS = PF / PL * 100

The values given above are inserted into the equation below and the solution is calculated:

PS = 25 / 97 * 100 = 25.77 (%)

Example Problem #2:** **

For this problem, the variables needed are provided below:

pipe fall (ft) = 50

pipe length (ft) = 1460

This example problem is a test of your knowledge on the subject. Use the calculator above to check your answer.

PS = PF / PL * 100** = ?**
