Radial Displacement Thin-wall Section (Open Ended)
| Radial Displacement Thin-wall Section (Open Ended) Formula | ||
| \( \Delta_r \;=\; \dfrac{ p \cdot r^2 }{ \lambda \cdot t }\) | ||
| Symbol | English | Metric | 
| \( \Delta_r \) = Radius Change | \( in \) | \( mm \) | 
| \( p \) = Pressure Under Consideration | \(lbf\;/\;in^2\) | \(Pa\) | 
| \( r \) = Radius to Point of Intrest | \( in \) | \( mm \) | 
| \( \lambda \) (Greek symbol lambda) = Elastic Modulus | \(lbf\;/\;in^2\) | \(Pa\) | 
| \( t \) = Wall Thickness | \( in \) | \( mm \) |
