Question

what is jurin's law?

Answer 1

Definition of Jurin's law. : a law of physics: the height of a capillary column of a liquid at a particular temperature is inversely proportional to the diameter of the tube.

Answer 2

Jurin's Law

Definition

When a capillary tube of insufficient length is positioned vertically in a liquid, liquid never comes out on its own, as it does when a tube of sufficient length is placed horizontally in a liquid.

$R h=\text { constant } \Rightarrow R_{1} h_{1}=R_{2} h_{2}$

where,

$R=$ radius of curvature of liquid meniscus and

$\mathrm{h}=$ height of liquid column.

When a tube is retained in an inclined position in a liquid while the vertical height h remains constant, the length of the liquid column remains constant.

$\cos \alpha=\frac{h}{l} \text { or } \mathrm{L}=\frac{h}{\cos \alpha}$

Surface tension causes liquids to rise (water in a glass capillary) or descend (mercury in a glass capillary).

Formula

$\mathrm{S}=\frac{R \rho g h}{2 \cos \theta}$

where,

R= radius of capillary tube,

h= height of liquid,

$\rho$ =density of liquid,

$\theta$ = angle of contact,

S= surface tension of liquid and

g= acceleration due to gravity
