Viscosity Units of Poise and Stokes

Viscosity is measured in pounds per square inch and stokes per square inch. Poise refers to dynamic viscosity, whereas stokes refers to kinematic viscosity. For different reasons, viscosity, which describes the consistency or "thickness" of a fluid, is divided into two categories.

The dynamic viscosity of a fluid tells us how much power is needed to move it at a specific speed. For example, When making a paste in a tube, we want it to have a certain dynamic viscosity. In this manner, squeezing the paste out of the tube won't be too difficult, nor will it be very runny, resulting in a large amount of paste being squeezed out even with a light squeezing pressure.

Kinematic viscosity is a term that describes the fluid's speed in response to a force. Kinematic viscosity is used in the production of fuels. We can model how fast fuel droplets will be blasted out of an injection nozzle owing to applied pressure by estimating the viscosity of fuels in terms of kinematic viscosity.

What is the Procedure for using the Poise-Stokes Converter?

Converting viscosity numbers is simple when you use the poise-stokes calculator. When utilising the poise-stokes converter, you can follow these steps:

  • Step 1: Input the density of the fluid.
  • Step 2: Enter the viscosity that you know.

When you enter a value for dynamic viscosity, the equivalent kinematic viscosity is displayed immediately, and vice versa. This converter can also be used to convert dynamic and kinematic viscosity units to other viscosity units. Simply enter your known viscosity value and select a different unit from the drop-down option.

What is the Procedure for Converting Stokes to Poise?

The following procedure is used to convert stokes to poise:

  • Step 1: Simply multiply the stokes value by the fluid density in grammes per cubic centimetre to convert stokes to poise. 
  • Step 2: If you have a density in kilogrammes per cubic metre, divide it by 1000 to get the density in grammes per cubic centimetre.
  • Step 3: Then, multiply it by the viscosity in stokes.

What is the procedure for converting poises to stock?

In some circumstances, we may want to express viscosity values as a function of type. It's simple to go from poise to stokes, and vice versa. However, we'll need the fluid's density to accomplish so. Once we have the information, we may convert it using the formula below: v = η/ρ

  • Where, ν - Kinematic viscosity 
  • η - Dynamic viscosity 
  • ρ - Density 

This equation can also be written as: νT ΓÇï = ηT ΓÇï /ρT ΓÇï

The subscripted T indicates that these parameters can only be observed in a certain fluid at a given temperature in this form. This means that the density of the fluid, and hence its viscosity, changes as the temperature of the fluid rises. We'll use the form without subscripted T for the sake of simplicity. We can convert stokes to poise using our conversion formula; η = ρ x v

FAQs on Poise-Stokes Converter

1. What is the definition of kinematic viscosity?

Kinematic viscosity indicates the fluid's speed as a result of an applied force. This is not to be confused with dynamic viscosity, which refers to the amount of force necessary to move fluid at a specific speed.

2. What is the difference between poise and stroke?

One stroke is equal to one poise multiplied by the fluid density in g/cm^3. Square metres per second (m^2/s) is the SI unit for kinematic viscosity.

3. What is the procedure for converting viscosity to dynamic viscosity?

Density is a key distinction between dynamic and kinematic viscosity measurements. Density is a useful tool for converting between kinematic and dynamic viscosity measurements. The conversion formula is Kinematic (cSt) x Density = Dynamic (cP)

4. Viscosity is measured in what unit?

For dynamic viscosity, we use poise, while for kinematic viscosity, we use stokes. By multiplying the poise value by the fluid's density in grammes per cubic centimetre, we may translate poise to stokes.

5. A poise has how many stokes?

The density of the fluid is constant, hence Stokes is exactly proportional to poise. The kinematic viscosity value in stokes is obtained by multiplying the dynamic viscosity in poise by the density in grammes per cubic centimetre. If the fluid density is 1 g/cm^3, the kinematic viscosity in stokes and poise will be the same.
