## 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.

- First, determine the force (lbf).
- Next, determine the length (ft).
- Next, determine the cross-sectional area (in^2).
- Next, gather the formula from above = PS = F*L*12 / (A*E).
- Finally, calculate the Pipe Stretch.
- 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) =** ** ?
