Explanation

Given: Diameter (D) of the capillary tube = m

Surface Tension (T) =

The angle of contact () =

Acceleration due to gravity (g) =

The temperature of water =

To Find: The height (h) of rising of water in the capillary tube

Solution:

Formula to find the height of the rise

The following expression is used to find the height (h) of rising of water in the capillary tube;

Where, is the density of water, and is the radius of the capillary tube.

Calculating the height of the rise in the capillary tube

Since the diameter of the capillary tube is , the radius of the tube will be;

And, at , the density of water is

Substituting all the required values in the above formula, we get;

Hence, the water will rise in a capillary tube to a height of
