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. One particular use of kinematic viscosity is for fuels. 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. Online calculator, figures and tables with dynamic (absolute) and kinematic viscosity for air at temperatures ranging -100 to 1600☌ (-150 to 2900☏) and at pressures ranging 1 to 10 000 bara (14. Viscosity, which describes a fluid's consistency or "thickness," comes in these two types for some distinct reasons. Poise is a unit of measurement used particularly for dynamic viscosity, while stokes is for kinematic viscosity. Kinematic viscosity of ethane at varying temperature and 1, 10 and 100 bara (14.Poise and stokes are units of measure used to quantify viscosity. ![]() See also other properties of Ethane at varying temperature and pressure: Density and Specific Weight, Specific heat (heat capacity) and Thermal conductivity, and Thermophysical properties at standard conditions,Īs well as dynamic and kinematic viscosity of air, ammonia, benzene, butane, carbon dioxide, ethanol, ethylene, methane, methanol, nitrogen, oxygen, propane and water.ĭynamic and kinematic viscosity of gaseous ethane at atmospheric pressure and varying temperature:ĭynamic and kinematic viscosity of liquid ethane at atmospheric pressure and varying temperature:ĭynamic viscosity of ethane at varying temperature and 1, 10 and 100 bara (14.5, 1 psia): Kinematic viscosity can be obtained by dividing the dynamic viscosity of a fluid by its density. Absolute or dynamic viscosity is used to calculate Reynolds Number to determine if a fluid flow is laminar, transient or turbulent. For further definitions, go to Absolute (dynamic) and kinematic viscosity. While the kinematic viscosity is given as cSt, m 2/s, and ft 2/s The viscosity of a fluid is a measure of its resistance to gradual deformation by shear stress or tensile stress. The output dynamic viscosity is given as Pa*s, N*s/m 2, cP, mPa*s, lb f*s/ft 2 and lb m/(ft*h), Use this program to convert the units of the kinematic viscosity. ![]() mm 2 /s (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. The calculator below can be used to calculate ethane dynamic or kinematic viscosity at given temperatures and atmospheric pressure. The kinematic viscosity is defined as the dynamic viscosity divided by density (nh/r). Conversion between dynamic and kinematic viscosity. Tabulated values of ethane viscosity and viscosity units conversion are given below the figures. Absolute or dynamic viscosity is used to calculate Reynold's Number to determine if a fluid flow is laminar, transient or turbulent. V/Y also represents the velocity gradient (sometimes referred to as shear rate). The viscosity of a fluid is a measure of its resistance to gradual deformation by shear stress or tensile stress.įor further definitions, go to Absolute (dynamic) and kinematic viscosity. The force necessary to move a plane of area A past another in a fluid is given by Equation 2.2.1 where V is the velocity of the liquid, Y is the separation between planes, and is the dynamic viscosity.
