Determination of viscosity of liquids

WebAbstract. Viscosity is a fundamental characteristic property of all liquids. When a liquid flows, it has an internal resistance to flow. Viscosity is a measure of this resistance to flow or shear. Viscosity can also be termed as a drag force and is a measure of the frictional properties of the fluid. Viscosity is a function of temperature and ... WebApr 6, 2024 · Kinematic Viscosity. Kinematic viscosity is a type of viscosity calculated by dividing the fluid mass density by the dynamic fluid, viscosity, or absolute fluid viscosity. It's also known as momentum diffusivity from time to time. Kinematic viscosity is measured in terms of time and fluid area.
