Unrestrained Pipe Expansion

Written by Jerry Ratzlaff on . Posted in Fluid Mechanics

formula

\(l_{UR} =  \frac { \Delta l  }   { \alpha \Delta T  }   \)

Where:

\(l_{UR}\) = unrestrained pipe length

\(\Delta l\) = pipe length change due to temperature change

\(\alpha\) = coefficient of thermal expansion

\(\Delta T\) = temperature change

Solve for:

\(\Delta l = l_{UR} \alpha \Delta T   \)

\(\alpha = \frac { \Delta l }   { l_{UR} \Delta T }   \)

\(\Delta T = \frac { \Delta l }   { l_{UR} \alpha }   \)
