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
