Write the formula for the height of a liquid column in a capillary tube.
(N/A) The height $h$ of a liquid column in a capillary tube is given by the formula:
$h = \frac{2T \cos \theta}{r \rho g}$
Where:
$T$ is the surface tension of the liquid.
$\theta$ is the angle of contact between the liquid and the capillary wall.
$r$ is the radius of the capillary tube.
$\rho$ is the density of the liquid.
$g$ is the acceleration due to gravity.
$h = \frac{2T \cos \theta}{r \rho g}$
Where:
$T$ is the surface tension of the liquid.
$\theta$ is the angle of contact between the liquid and the capillary wall.
$r$ is the radius of the capillary tube.
$\rho$ is the density of the liquid.
$g$ is the acceleration due to gravity.

View Solution$A$ capillary tube is immersed vertically in water,and the water rises to a height $h_1$ on the Earth's surface. When this arrangement is taken into a mine of depth $d$ below the Earth's surface,the height of the water column is $h_2$. If $R$ is the radius of the Earth,the ratio $\frac{h_2}{h_1}$ is:

View SolutionThree liquids have the same surface tension and densities $\rho_1, \rho_2$,and $\rho_3$ $(\rho_1 > \rho_2 > \rho_3)$. In three identical capillaries,the rise of the liquid is the same. The corresponding angles of contact $\theta_1, \theta_2$,and $\theta_3$ are related as:
