Newtonian fluid
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.
