Q. What is the stalagmometric method?

Answer

One of the most frequent approaches of determining surface tension is the stalagmometric technique. The surface tension of a fluid may be calculated using an equation if we know the surface tension of water, which is 72 dyne/cm. Surface tension may be calculated using the equation with increasing accuracy as more droplets are weighed. Maintaining a clean stalagmometer is essential for accurate readings. Commercially available tubes for the stalagmometric technique come in 2.5-, 3.5-, and 5.0-millimeter diameters (ml). Small volumes and low viscosity require the 2.5-ml size, whereas slightly viscous fluids require the 3.5-ml size, and large quantities and high viscosity require the 5.0-ml size. Most liquids may be contained within a container of 2.5 ml.
