Volume Differential

Volume Differential Formula
$\Delta V \;=\; V_f - V_i$
Symbol	English	Metric
$\Delta V$ = volume differential	$in^3$	$mm^2$
$V_f$ = final volume	$in^3$	$mm^2$
$V_i$ = initial volume	$in^3$	$mm^2$

Volume differential, abbreviated as $\Delta V$ , is the difference between an expanded or reduced volume of a liquid.
