Online Water Surface Tension Calculator: Want to know what are the methods to measure the surface tension like Surface tension calculation capillary tube method. Just continue you read to further modules in the surface tension calculator tool and learn the surface tension definition, manual steps to find the surface tension of a liquid with surface tension formula. Also, take help of the provided solved example on surface tension calculation for better understanding.

Definition of Surface Tension

Surface tension is a liquid property that confront the force acting thereon. It is made by the internal attraction of molecules at a boundary. The energy needed to stretch a unit change of surface area is called surface tension.


What is Surface Tension Formula and Unit?

The formula that is used to calcukate the surface tension is expressed as below:

γ = 1/2 * F / L

Where,

  • γ is the surface tension (N/m)
  • F is the force (N)
  • L is the length (m)

The unit of surface tension in SI unit system is Newton per Mtere or N/m. In CGS unit system the surface tension units is dyn/cm.


How Do You Calculate Surface Tension?

The steps that have to be noted and followed while calculatig surface tension is as follows:

  1. Initially, you have to find the force acting on the object.
  2. Later on, just indentify the length of the object.
  3. Now, take the help of the surface tension formula ansubstitute the values in it.
  4. Evaluate the experssion and get the final result of surface te

Surface Tension Calculation Example

Example:

Compute the surface tension of a given liquid whose dragging force is 8 N and the length in which the force acts is 4 m?

Solution:

Given inputs are

F = 8 N
L = 4 m

Now apply the surface tension formula;

ie., γ = 1/2 * F / L

⇒ γ = 1/2 * 8/4

⇒ γ = 1.3333333333333333

Hence, the surface tension of a given liquid is1.3333333333333333 N/m.
