2 hours ago A Newtonian fluid is a fluid in which the viscous stresses arising from its flow, at every point, are linearly correlated to the local strain rate—the rate of change of its deformation over time. That is equivalent to saying those forces are proportional to the rates of change of the fluid's velocity vector as one moves away from the point in question in various directions.

### How does stokes'law relate to fluid velocity?

Log in or sign up to add this lesson to a Custom Course. Now, let's look at how Stokes' law ties all of this together in equation form. This equation tells us that the larger the ball bearing, the larger the force on it when it is moving through a fluid at terminal velocity.

### How does Stokes law relate to the environment?

This aids in keeping the environment cleaner. Stokes' law defines the drag force that exists between a sphere moving through a fluid with constant velocity. Viscosity is the resistance of a fluid to flow, and with increasing viscosity, the sphere's velocity drops. When the radius of the sphere increases, the drag force increases too.

### How to calculate the smoothness of Stokes law?

Stokes’ Law will suffice as a sufficient model if the flow is smooth and non-turbulent. We can determine this smoothness by calculating Reynolds number: where Re is Reynolds number, is the fluid density, V is the characteristic velocity, d is the characteristic flow length, and is the fluid viscosity.

### What is the net downward force of Stokes law?

Stokes' law describes the settling of spheres in a Newtonian fluid. A spherical particle placed in a Newtonian fluid will sink if the buoyant force does not match or exceed the gravitational force on the sphere. The net downward force on a sphere is the difference between the settling force and the buoyant force.
