How Is Viscosity Defined?

by

How Is Viscosity Defined? It describes the internal friction of a moving fluid. A fluidwith large viscosity resists motion because its molecular makeup gives it a lot of internal friction. How is viscosity determined? There are several formulas and equations to calculate viscosity, the most common of which is Viscosity = (2 x (ball density

What Is The Principle Of Viscometer?

What Is The Principle Of Viscometer? These viscometers use the principle of ‘rotational viscometry‘, i.e. their measurement of product viscosity is based upon immersing a specifically selected spindle within a sample of the product followed by measurement of the torque required to rotate the spindle at a set speed whilst immersed within the product sample
