Posted by Art Gatenby on Sep 23, 2013 12:42:00 PM

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.

How Does Surface Tension Relate to Viscosity?

Posted by Art Gatenby on Jan 17, 2011 9:58:00 PM

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.

Having Trouble Performing a duNouy Ring Test in Thick Samples?

Posted by Art Gatenby on Nov 15, 2010 3:29:00 PM

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.”
