How to Calculate Surface Tension?
The surface Tension of any substance can easily be calculated using the surface tension formula as discussed above in the article. Let’s take an example to understand the calculation of Surface Tension in detail.
Example: Find the surface tension of the liquid with a dragging force of 12 N when the length at which the force acts is 4 m.
Solution:
Given,
F = 12 N
L = 4 mAccording to the Surface Tension formula, T = F/L
T = 12/4
T = 3 N/m
Surface Tension
Surface tension is the ability of fluid surfaces to contract into the smallest possible surface area. Have you ever found that even after filling a glass full of water, you can only add a few more drops before it spills? Have you ever lost a thermometer and watched how the mercury reacts as it falls? All of which are caused by the surface tension of the surface. Its isolated surface behaves like a strong rubber membrane due to the suppressive force in the fluid molecules. As a result, the individual surface of the fluid is still in a state of stress and tends to have the smallest field. Thus, Surface Tension refers to the tension on the fluid’s individual surface.
