Abstract
Viscosity in a layman’s knowledge is the thickness of a fluid, scientifically, it is the measure of a fluid’s internal friction. A fluid’s viscosity is determined by viscometers, which is part of a wider science called rheometry. Oil is any neutral, non-pola chemical substance that is a viscous liquid at ambient temperature. The s/i. of viscosity is the Pascal Second[Pa.S]. the Gaussian unit of viscosity is the poise (pdyne s/cm). Stephen and Lucas, 1996). Kinematic viscosity is defined as a measure of flow of a liquid under gravity. Therefore the more viscous the oil is the slower it flows and the less viscous the oil is the faster it flows.
