Enter the force (lbf), the length (ft), and the cross-sectional area (in^2) into the Pipe Stretch Calculator. The calculator will evaluate the Pipe Stretch.

## Pipe Stretch Formula

The following formula is used to calculate the Pipe Stretch.

PS = F*L*12 / (A*E)

Variables:

• PS is the Pipe Stretch (inches)
• F is the force (lbf)
• L is the length (ft)
• A is the cross-sectional area (in^2)
• E is the modulus of elasticity (psi, 30 * 10^6 for metal)

## How to Calculate Pipe Stretch?

The following steps outline how to calculate the Pipe Stretch.

1. First, determine the force (lbf).
2. Next, determine the length (ft).
3. Next, determine the cross-sectional area (in^2).
4. Next, gather the formula from above = PS = F*L*12 / (A*E).
5. Finally, calculate the Pipe Stretch.
6. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem:

Use the following variables as an example problem to test your knowledge.

force (lbf) = 500

length (ft) = 3

cross-sectional area (in^2) = 20

PS = F*L*12 / (A*E) =  ?
