Dynamic viscosity
Dynamic viscosity (also known as absolute viscosity) is the measurement of the fluid’s internal resistance to flow.It is the tangential force required to move one horizontal plane of a fluid with respect to another.
Dynamic viscosity = shearing stress / shearing rate change
The equation is written
η = τ / γ
We have:
η: Dynamic viscosity
τ: Shearing stress
γ: Shear rate
