Frequently Asked Questions
-
What does one decipoise represent?
-
One decipoise is a CGS unit of dynamic viscosity equal to one tenth of a poise, measuring a fluid's resistance to shear flow, equivalent to 0.01 pascal-second.
-
When should I use pound-force second per square inch as a viscosity unit?
-
It is used mainly for reporting the viscosity of very thick greases, heavy oils, and certain polymer melts, especially in US engineering and industrial contexts.
-
Why is this conversion important for industrial processes?
-
It facilitates interpreting and reporting viscosity data across different unit systems often encountered in industries like lubrication, petroleum refining, and polymer processing.
Key Terminology
-
Decipoise [dP]
-
A CGS unit of dynamic viscosity equal to one tenth of a poise, measuring fluid internal resistance to shear flow; 1 dP = 0.01 pascal-second.
-
Pound-force second/sq. inch (lbf·s/in²)
-
An Imperial/US customary unit of dynamic viscosity equal to one pound-force second per square inch, used especially for very viscous materials.
