Length Differential
Length differential, abbreviated as \(\Delta l\), is the difference between an expanded or reduced length of an object.
Length Differential formula
| \(\large{ \Delta l = l_f - l_i }\) |
Where:
| Units | English | Metric |
| \(\large{ \Delta l }\) = length differential | \(\large{ft}\) | \(\large{m}\) |
| \(\large{ l_f }\) = final length | \(\large{ft}\) | \(\large{m}\) |
| \(\large{ l_i }\) = initial length | \(\large{ft}\) | \(\large{m}\) |
Related Length Differential formula
| \(\large{ \Delta l = l_{ur} \; \alpha \; \Delta T }\) | (unrestrained pipe length) |
Where:
\(\large{ \Delta l }\) = length differential
\(\large{ \Delta T }\) = temperature differential
\(\large{ \alpha }\) (Greel symbol alpha) = thermal expansion coefficient
\(\large{ l_{ur} }\) = unrestrained pipe length
