Capillary Action

a1v 1=a 2 v 2...

Question

a1v1=a2v2=V. What is V here? If it is volume, how this relation is true?

Solution

Here V is simply volume flow rate.
The volumetric flow rate (also known as volume flow rate, rate of fluid flow or volume velocity) is the volume of fluid which passes per unit time; usually represented by the symbol Q (sometimes V̇). The SI unit is m3/s (cubic metres per second). Another unit used is sccm (standard cubic centimeters per minute).
