Newtonian fluid

Newtonian fluid is a type of fluid, whose shear stress is proportional to velocity gradient.

Newtonian fluid can be expressed with the following equation:



where;
τ: Shear stress [Pa]
μ: Viscosity coefficient [Pa・s]
du/dy: Velocity gradient [1/s]

Examples of Newtonian fluid include air and water.
