Unrestrained Pipe Expansion

Unrestrained Pipe Expansion formula

\(\large{ l_{ur} =  \frac { \Delta l  }   { \alpha \; \Delta T  }   }\)

Where:

\(\large{ l_{ur} }\) = unrestrained pipe length

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

\(\large{ \alpha }\) = thermal expansion coefficient

\(\large{ \Delta T }\) = temperature change

Solve for:

\(\large{ \Delta l = l_{ur} \; \alpha \; \Delta T   }\)

\(\large{ \alpha = \frac { \Delta l }   { l_{ur} \; \Delta T }   }\)

\(\large{ \Delta T = \frac { \Delta l }   { l_{ur} \; \alpha }   }\)
