WebFeb 19, 2024 · A Newtonian fluid is one that keeps a constant value of viscosity across all shear rates. They get this moniker because they follow the formula set out by Isaac Newton in his law of fluid mechanics. Fluids that don’t exhibit constant viscosity across all shear rates are known as non-Newtonian fluids. WebNewtonian fluid, a fluid in which viscosity is independent of the shear rate, e.g. water, urine, cerebrospinal fluid. Non-Newtonian fluid , a fluid in which viscosity does depend on …
