Viscosity
There are many definitions of Viscosity by different people
but If we review all of the definition of Viscosity first we have to know about
laminar flow. When single layer of liquid substance is move against the other
layer with no transfer of matter to the other is a laminar flow. Viscosity is
the level of friction in the middle of these layers. It depends on certain
factors, maximum speed that is exist in one fluid layer that is known as
‘turbulence’ can move against another, after that mass transfer actually
occurs.
Why It’s Important to Measure Viscosity
A huge number of industries used viscometer now days to
measure the viscosity of liquid’s. For a product to be useful, it is necessary
to maintain their qualities and nature. Grease melted on high temperature in
the machine shops that’s why grease don’t stick to the surface as required that
is the reason companies manufacture the grease must need to identify the
several viscosity rates in proportion to the temperature on which it is tested.
By measuring the viscosity using the viscometer will help industries to
generate the products that will satisfy their clients in better way and
consistent in quality. Most of times the viscosity data is collected for
detecting, observing other attributes of the material because when we know some
other properties of material it is easier for us to measure the viscosity.
Hence it is very significant tool for characterization of the material.
Viscosity and Temperature
One of the basic factors that have the major effect on the
rheological behavior of the material is the temperature. Majority of the
substance are sensitive due to this sensitivity substance change on different
temperatures. Results of viscosity of material can be change due to minor
change in temperature. There are many other substances which are not much
sensitive that temperature affects their viscosity. You must have the knowledge
about the viscosity of different materials, for processing that plants which
deals with motor oil.
