One of the ways to describe surface tension in fluids is: the property of a liquid’s surface that resists force. It serves as a barrier to foreign materials and holds the liquid together. This ever-present property is caused by unbalanced forces on surface molecules that pull toward the main part of the liquid.

Within the catalog of questions we are asked is a  category related to Calibrating duNouy Ring Tensiometers. The subject matter ranges from how, why and what is proven?

I guess the immediate and wise-assed answers are:

You may recall that I promised to offer my interpretation as to how Surface Tension is related to Viscosity.

To begin with, liquid surface tension and viscosity share a common trait: they both involve properties of fluids. After that, things start to get murky.

My musings were interrupted this week with a pressing challenge. It was stated like this:

 “My duNouy ring kept falling off the arm hook when attempting to immerse it into a high-viscosity sample.”
