Why Calibrate a CSC DuNouy Tensiometer?

Posted by Art Gatenby on Sep 13, 2011 11:14:00 AM

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:

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.”

Is Consistency Viscosity? Not really!

Posted by Art Gatenby on Jan 8, 2009 10:46:00 AM

We make the Bostwick Consistometer. The Bostwick is used extensively to measure the consistency of sauces and condiments. It has strong application in the quality control departments of ketchup and mustard producers. Results from a Bostwick Consistometer have been used for more than six decades to control the quality of many of the foods you use.

Surface Tension and Interfacial Tension

Posted by Art Gatenby on Nov 10, 2008 3:34:00 PM

I was musing, the other day on the designs of two ring tensiometers. One of them is called an interfacial tensiometer and the other simply a tensiometer. The plain tensiometer works only with an upward pull and the interfacial works with both an upward pull as well as a downward push. Before I get to my question a couple of definition might be useful.
