Dynamic Viscosity Calculator

Enter the shear stress, distance between layers, and shear velocity into the calculator to determine the dynamic viscosity.

Dynamic Viscosity Formula

The following formula is used to calculate a dynamic viscosity.

u = t * (y/v)

  • Where u is the dynamic viscosity
  • t is the shear stress
  • y is the distance between layers
  • v is the shear velocity

Dynamic Viscosity Definition

A dynamic viscosity is defined as the resistance to movement of a fluid due to internal attractions and frictions within the fluid.

Dynamic Viscosity Example

How to calculate dynamic viscosity?

  1. First, determine the shear stress.

    Calculate the shear stress acting on the fluid due to the movement and the walls of the container.

  2. Next, determine the distance between layers.

    This will be the distance between the surfaces containing the fluid.

  3. Next, determine the shear rate.

    Calculate the rate of the shear that is being applied to the fluid.

  4. Finally, calculate the dynamic viscosity.

    Using the formula, calculate the dynamic viscosity.


What is dynamic viscosity?

Dynamic viscosity is the resistance to movement of a fluid due to internal fluid frictions caused by a moving fluid against a stationary surface.
