Definition - What does Rotational Viscometer mean?
Rotational viscometer is generally used to define viscosity of liquids that do not only rely on temperature and pressure. However, it can also be used to test and analyze the behavior of non-Newtonian liquids.
Petropedia explains Rotational Viscometer
Rotational viscometer is a device that collects data on materials viscosity performance under various temperature conditions. The rotational viscometer fundamentally is of two parts- one is the head component with a motor and the other is spindle that is motor-powered. It can be used to ensure the correct measurement of both Newtonian and non-newtonian fluids. Newtonian fluids are that shear stress and shear rate are in direct proportion and non-newtonains don’t display the lineal relation between shear stress and shear rate. It is mainly used by manufacturing or sourcing enterprises such as paint, inks, gels, adhesives, juices, etc.
