Introduction
Viscosity is one of
the important physical properties of many fluid products. Consumers
often care about the consistency of products that they buy. Any
variation in the viscosity of a product from time to time can be
an indication of unreliability of a product. For lubricants, motor
oils and cooking oils the viscosity is also sensitive to the
temperature and varies in different temperatures. This can cause
some other problems. For example if you use a motor oil that
becomes very viscose in cold weather, you will have trouble in
starting the engine in winters. |
