GENERAL KNOWLEDGE

Detailed explanation-1: -A viscometer (also called viscosimeter) is an instrument used to measure the viscosity of a fluid. For liquids with viscosities which vary with flow conditions, an instrument called a rheometer is used.

Detailed explanation-2: -There are several formulas and equations to calculate viscosity, the most common of which is Viscosity = (2 x (ball density – liquid density) x g x a^2) ÷ (9 x v), where g = acceleration due to gravity = 9.8 m/s^2, a = radius of ball bearing, and v = velocity of ball bearing through liquid.

Detailed explanation-3: -Viscometers are instruments that measure the fluid flow and viscosity of liquids. The viscosity of a liquid can affect its performance, whether this is pumping or piping it, or how it performs for dipping and coating. Measuring viscosity, therefore, applies to a wide range of materials, including: Oil.
