What is a stoke equal to?
Stokes (symbol: St) + centiStokes (symbol: cSt) This is the CGS unit, equivalent to square centimetres per second (cm2 s–1). One stokes is equal to the viscosity in poise divided by the density of the fluid in grams per cubic centimetre (g·cm–3).
What is kinematic viscosity equal to?
Kinematic viscosity is absolute viscosity divided by density, e.g. Kinematic viscosity at t 0 = absolute viscosity at t ° density at t o . Temperature, viscosity and density must be in consistent units, and under the same conditions.
How do you find kinematic viscosity in Stokes?
Kinematic viscosity can be obtained by dividing the dynamic viscosity of a fluid by its density. The Stokes(St) is the cgs physical unit for kinematic viscosity, named after George Gabriel Stokes, where 1 St = 10-4 m2/s. It is also expressed in terms of centistokes (cSt or ctsk).
What is equal to 1 Pa s in viscosity?
›› More information from the unit converter The answer is 0.1. We assume you are converting between Pascal-second and poise. You can view more details on each measurement unit: Pa-s or poise The SI derived unit for dynamic viscosity is the pascal second. 1 pascal second is equal to 1 Pa-s, or 10 poise.
What are the units of viscosity and kinematic viscosity?
Kinematic viscosity has SI units of m2 s−1. The physical unit for kinematic viscosity is the stokes (St), named after George Stokes. It is sometimes expressed in terms of centistokes (cS or cSt); 1 stokes = 100 centistokes = 1 cm2 s−1 = 0.0001 m2 s−1.
How do you convert Stoke to poise?
Stokes = A x Poise / (Fluid Density) where A = 1000, if the fluid density is measured in kg per cubic meter. That is, at standard pressure and 15 C temperature, the dynamic viscosity of air is roughly 0.000173 poise, and the kinematic viscosity of air is roughly 0.141 stokes.
How is kinematic viscosity calculated?
Kinematic viscosity is measured by noting the time it takes oil to travel through the orifice of a capillary under the force of gravity (Figure 1). The orifice of the kinematic viscometer tube produces a fixed resistance to flow. Different sized capillaries are available to support fluids of varying viscosity.
How do you convert poise to Stoke?
What is the unit of viscosity?
The unit of viscosity is newton-second per square metre, which is usually expressed as pascal-second in SI units.
Which of the following is a unit of kinematic viscosity?
(2) Kinematic Viscosity: The ratio of dynamic viscosity to density appears frequently and this ratio is given by the name kinematic viscosity. Its unit is Stoke or m2/s (1 stoke = 0.0001 m2 /s).
How do you convert viscosity to kinematic viscosity?
Density actually provides a way to convert between a kinematic and a dynamic viscosity measurement. The formula for the conversion is: Kinematic (cSt) x Density = Dynamic (cP) Dynamic (cP) / Density = Kinematic (cSt)
