Commonly used viscosity unit - Degree Engler
Degree Engler is used in Great Britain as a scale to measure kinematic viscosity. Unlike the Saybolt and Redwood scales, the Engler scale is based on comparing a flow of the substance being tested to the flow of another substance - water. Viscosity in Engler degrees is the ratio of the time of a flow ...

Commonly used viscosity unit - Saybolt Universal Seconds
Saybolt Universal Seconds(SUS) is used to measure viscosity. The efflux time is Saybolt Universal Seconds required for 60 milliliters of a petroleum product to flow through the calibrated orifice of a Saybolt Universal viscometer, under carefully controlled temperature and as prescribed by test method ...

Viscosity and Reference Temperatures
The viscosity of a fluid is highly temperature dependent and for either dynamic viscosity or kinematic viscosity to be meaningful, the Reference Temperature must be quoted. In ISO 8217 the reference temperature for a residual fluid is 100 degree Celsius. For a distillate fluid the reference temperature ...

Two related measures of fluid viscosity
There are two related measures of fluid viscosity, knows as dynamic(absolute) viscosity and kinematic viscosity.Dynamic(absolute) viscosity is the tangential force per unit area required to move one horizontal plane with respect to the other at unit velocity when maintained an unit distance apart by ...

Introduction of Viscosity
The viscosity of a fluid is an important property in the analysis of liquid behavior and fluid motion near solid boundaries.The viscosity is the fluid resistance to shear or flow and is a measure of the adhesive/cohesive of frictional fluid property. The resistance is caused by intermolecular friction ...

Coulometric water determination
Coulometric water determination is primarily used for the determination of small amounts of water. Larger amounts of water require a lot of time and/or may exceed the water capacity of the Karl Fischer reagent, which could lead to incorrect results. Metrohm Karl Fischer Coulometers work in a determination ...

What is a Muffle Furnace Used For?
A muffle furnace has separate combustion and heating chambers. This means the gases, ash and residue of combustion do not contaminate the heated material. Often used in scientific research, the muffle furnace allows the study of heated materials without inclusion of outside materials from the combustion ...

What is viscosity?
Viscosity is a measure of the resistance of a fluid which is being deformed by either shear stress or tensile stress. In everyday terms (for fluids only), viscosity is "thickness" or "internal friction". Thus, water is "thin", having a lower viscosity, while honey is "thick", having a higher viscosity. ...
