corn starch combined with water – it gets thicker when stirred faster fluid. wall paint – as you stir wall paint, it becomes increasingly fluid and liquidy. They get this moniker because they follow the formula set out by Isaac Newton in his law of fluid mechanics.įluids that don’t exhibit constant viscosity across all shear rates are known as non-Newtonian fluids.Įxamples of some Newtonian fluids are gases, oil, water, alcohol, petroleum, etc.Įxamples of some non-Newtonian fluids include: Kinematic viscosity in Newtonian and non-Newtonian fluidsĪ Newtonian fluid is one that keeps a constant value of viscosity across all shear rates.
The table below contains kinematic viscosity values for some common fluids. When used in this equation, the viscosity μ is often referred to as dynamic viscosity or absolute viscosity. Kinematic viscosity is measured in units of (length) 2/time – most commonly using centiStokes (cSt), where 1 Stoke = 1 cm 2/s.
