# 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.

### 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.
