![]() ![]() By comparison, light lubricating oils may have a viscosity of 100 or 200 SSU. ![]() ![]() For example, water has a viscosity of approximately 31 SSU at 60 degrees Fahrenheit (F). This refers to the length of time it takes for a measured quantity of liquid at a specific temperature to drain from a container with a measured orifice in the bottom. A common way to measure kinematic viscosity is the Saybolt Seconds Universal (SSU) (see Image 2). Kinematic viscosity is designated by the Greek letter ν (Nu). It is common to express viscosity relative to its density, which is known as kinematic viscosity. Example of SSU viscosity measurement)Ībsolute viscosity, μ (Mu), is the quotient of the shear stress (or force per unit area) divided by the shear rate. ![]()
