A poise (P), named after Jean Léonard Marie Poiseuille, who also derived the Poiseuille's law equation, has a value equivalent to 0.1 pascals-second (Pa⋅s). Now that we know the difference between the two types of viscosities, let's go back to the measurement units. By determining the viscosity of fuels in terms of kinematic viscosity, we get to model the speed fuel droplets that will be sprayed out of an injection nozzle due to applied pressure. (The calculator on this site is for informative purposes only and we make no claims as to the accuracy, completeness or fitness for any particular purpose of the results produced by our calculators. One particular use of kinematic viscosity is for fuels. Conversion between dynamic and kinematic viscosity. On the other hand, we use kinematic viscosity to describe the speed of the fluid due to an applied force. Learn more about squeezing pressure on a container with fluids by checking out our manometer calculator. That way, it won't be either too hard to squeeze the paste out of the tube or too runny that a lot of paste comes out, even with a little squeezing pressure. When formulating the mixture of, let's say, a paste in a tube, we want the paste to have a specific dynamic viscosity. The dynamic viscosity tells us how much force is required for a fluid to move at a particular speed. Viscosity, which describes a fluid's consistency or "thickness," comes in these two types for some distinct reasons. Benzene - Dynamic and Kinematic Viscosity vs. What is the relationship between dynamic viscosity and kinematic viscosity for Newtonian materials The viscosity of Hg is 1.661 10-3 Pas at 0 C and 1.476 10-3 Pas at 35 C. Poise is a unit of measurement used particularly for dynamic viscosity, while stokes is for kinematic viscosity. Air - Dynamic and Kinematic Viscosity Online calculator, figures and tables with dynamic (absolute) and kinematic viscosity for air at temperatures ranging -100 to 1600C (-150 to 2900F) and at pressures ranging 1 to 10 000 bara (14.5 - 145000 psia) - SI and Imperial Units. The output dynamic viscosity is given as Pas, Ns/m 2, cP, mPas, lb f s/ft 2 and lb m / (fth), while the kinematic viscosity is given as cSt, m 2 /s, and ft 2 /s. Fill in zero (0) in the weight percent column (Wt%) if Base oil #3 and-or Base oil #4 are not part of the mixing viscosities.Poise and stokes are units of measure used to quantify viscosity. The calculator below can be used to estimate oxygen dynamic or kinematic viscosity at given temperatures and atmospheric pressure. The kinematic viscosity ( 'nu') is the dynamic viscosity of the medium divided by its density. Relationship between dynamic and kinematic viscosity v. Dynamic viscosity increases for gases as temperature rises.
You can use this calculator to predict mixing viscosities of 2-4 base oils. The dynamic viscosity drops off very quickly for liquids as their temperatures increase. Viscosity temperature is not required but must be the same for all base oils viscosities. This calculator allows users to input the dynamic viscosity and kinematic viscosity of a substance and calculates its density using the provided values. Fill in zero 0 (or leave default “0”) in Wt % if not included in the blending calculations.
Please note: Leave the default value of “1” in the viscosity field if blending less than two liquids. If you don’t want to include 3rd and 4th base oils, fill any value (>1) in the viscosity cell and zero (0) in the Wt%.Ĥ- Repeat the same for Base Oil #4 by filling in the viscosity and Wt% of the Base oil.ĥ- Click Calculate to predict the mixing viscosity of the blend. Viscosity Calculator #3ġ- Fill the viscosity of Base oil #1 and weight percent (Wt%) in the third (Wt%) column.Ģ- Fill in the viscosity of Base Oil #2 and weight percent (Wt%) in the next column.ģ- Fill in the weight percent (Wt%) and Base oil #3 viscosity in the 3rd row. Module #3: Mixing viscosities calculator to blend or mix more than two base fluids.
