Stokes Law Calculator

Stokes Law Calculator is an online tool that finds the terminal velocity on entering the inputs viscosity, density of fluid, and density and diamter of particle in a fraction of seconds. Make your calculations quite simple using the handy calculator and get the terminal velocity of the object easily.

Stokes Law Calculator: Analyzing a speherical particle's motion in a vertical tube filled with viscous liquid and need any assistance? Don't bother anymore as our flexible and easy to use Stokes Law Calculator does that all for you. Read on to know what does stokes law mean, viscosity definition and how to find terminal velocity using stokes law, etc.

Viscosity - Definition

Viscosity of a fluid deals with its resistance to shearing stresses. A fluid having higher resistance is more resistant to sheer stresses. Units of Viscosity are Pascal Times Second(Pa.s)

Stokes Law Terminal Velocity Formula

As per the stokes law terminal velocity of a particle in a viscometer filled with viscous fluid is given by the formula v = gd²(ρp - ρm)/(18μ)

  • Where v is the terminal velocity of a spherical particle
  • g is the gravitational acceleration and is equal to 9.80665 m/s²
  • d is the diameter of the particle
  • ρp is the density of the particle
  • ρm is the density of the fluid
  • μ is the dynamic viscosity of the fluid

How to calculate Terminal Velocity using Stokes Law?

Follow the simple guidelines provided below to find terminal velocity using the stokes law. They are as such

  • Firstly, determine the diameter of the particle.
  • Next, check for the density of the particle
  • Later, determine the density of the fluid, viscosity of the fluid
  • Simply, input all these parameters in the equation to find the terminal velocity.
  • Simplify the equation further and find out the terminal velocity quickly.

Frequently Asked Questions on Stoke's Law Calculator

1.What do you mean by Stokes Law?

Stokes Law tells us that a force that retards a sphere moving through viscous fluid is directly proportional to sphere radius, viscosity of the fluid, etc.

2. How to find the Terminal Velocity?

Terminal Velocity can be found using the formula v = gd²(ρp - ρm)/(18μ)

3. What are the Units of Viscosity?

Units of Viscosity are Pascal Times Second(Pa.s)

4. What is meant by Viscosity?

Viscosity of a fluid is nothing but the resistance to sheering stresses.
