All fluids have an internal friction between molecules, which determines how well fluid flows. Due to this internal friction, energy is required to move the liquid and viscosity is the measure of the resistance to flow. Fluids are categorized as Newtonian or non-Newtonian.

Newtonian fluids, such as water and some oils, are fluids that continue to flow at a given temperature, regardless of the forces acting on it. No matter how Viscosity lab it is stirred or mixed, Newtonian fluids will always behave in the same manner.

Newtonian fluids are generally Viscosity lab with flow and dip viscosity cups.

Non-Newtonian fluids, such as paints and ketchup, are fluids which change viscosity when a force is applied. There are several different categories and sub-categories of non-Newtonian fluids, they can be described as the following: Thixotropic - substances which are gel-like at rest but liquid when agitated, such as non-drip paints, tomato ketchup and most varieties of honey.

Rotational Viscosity Rotational viscometers are used to determine the viscosity of liquids which do not depend solely on temperature and pressure. Rotational viscometers consist of two parts - the head unit with a motor and a spindle that is driven by the motor.

The viscosity is determined by measuring the resistance of the spindle as it rotates in the sample. View Viscosity Reference Chart Infographic The process of flow through an orifice can often be use as a relative measurement and classification of viscosity.

This measured kinematic viscosity is generally expressed in seconds of flow time which can be converted into Centistokes using a viscosity disc calculator. A number of different types of Flow cup are available to suit specific standards. View Viscosity Reference Chart Infographic Elcometer viscosity dip cups are ideal for the quick testing of the viscosity of paints, varnishes and similar products during manufacturing processes.

Dip cups are dipped into the substance being tested and the viscosity is determined by the time it takes for the cup to empty with a steady flow.

Elcometer has a range of viscosity dip cups which includes Frikmar, Zahn, Shell, and Lory dip cups.


Viscosity Calibration Oils Viscosity calibration oils are used to check viscosity measurements. Elcometer offers both viscosity cup standard calibration oils as well as rotational calibration oils. Standard rotational calibration oils are made for use with Elcometer Rotational viscometers. Flow Measurement Elcometer offers various instruments that effectively measure the fluidity and flow of coatings, especially thick or paste-like materials such as paints or printing ink.

Both the Matthis Fluidometer, which comes with a sand timer, and the Daniel Flow Gauge emphasize principles of ease of use and simplicity.The most important system to the "health" of your engine is the lubication system.

Oils have changed a lot in the past few years, and a lot of confusing information is out there. Viscosity is defined as a liquid’s resistance to flow. Name a substance that has HIGH viscosity _____ Name a substance that has LOW viscosity _____ Different liquids have different viscosities due to their chemical makeup.
