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?
- First, determine the shear stress.
Calculate the shear stress acting on the fluid due to the movement and the walls of the container.
- Next, determine the distance between layers.
This will be the distance between the surfaces containing the fluid.
- Next, determine the shear rate.
Calculate the rate of the shear that is being applied to the fluid.
- Finally, calculate the dynamic viscosity.
Using the formula, calculate the 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.
