In this method of surface tension, a liquid drop is permitted to form on the capillary lower end, in the surface tension upper forces of tension supported to the outer periphery of the tube. The drop mass is dragged it down, when the force is balanced the drop are brakes at the bottom of the working device there is a glass in which the capillary is called a stalagmometer.
The drop breaks when forces are balanced. Working equipment has a glass in the lower part with the capillary this called as a stalagmometer. Then the surface tension is detected by calculating the number of droplets for the specified liquid.
