What is the CGS unit of poise? centimetre-gram-second A poise is the centimetre-gram-second (cgs) unit of viscosity. What is CGS unit of viscosity? The cgs unit of viscosity is poise (P) and this name has
What is the CGS unit of poise?
centimetre-gram-second
A poise is the centimetre-gram-second (cgs) unit of viscosity.
What is CGS unit of viscosity?
The cgs unit of viscosity is poise (P) and this name has been used in honor of a French physiologist Jean Léonard Marie Poiseuille. It is also commonly used particularly in ASTM standards, as centipoise (cP). Sometimes the unit centistokes (cSt) is also used.
Is poise SI unit or CGS unit?
A centipoise is one hundredth of a poise, or one millipascal-second (mPa⋅s) in SI units (1 cP = 10−3 Pa⋅s = 1 mPa⋅s)….Poise (unit)

How do you express viscosity in poise?
Question: The CGS unit for measuring the viscosity of a liquid is the poise (P): 1 P = 1 g/(s middot cm). The SI unit for viscosity is the kg/(s middot m). The viscosity of water at 0 degree C is 2.82 times 10^-3 kg/(s m).
What is a unit of viscosity?
The unit of viscosity is newton-second per square metre, which is usually expressed as pascal-second in SI units.
Which is the SI unit of viscosity?
Pascal-second
Dynamic viscosity: The SI physical unit of dynamic viscosity (μ) is the Pascal-second (Pa s), which is identical to 1 kg m−1 s−1. The physical unit for dynamic viscosity in the centimeter gram second system of units (cgs) is the poise (P), named after Jean Poiseuille.
What is the unit used for viscosity?
The unit of viscosity, accordingly, is newton-second per square metre, which is usually expressed as pascal-second in SI units.
What is viscosity and its unit?
The definition of viscosity is as follows: Viscosity is a measure of a fluid’s resistance to flow. The SI unit of viscosity is poiseiulle (PI). Its other units are newton-second per square metre (N s m-2) or pascal-second (Pa s.) Thus, upon heating, liquids flow more easily, whereas gases flow more slowly.
What are the different units of viscosity?
The SI unit of dynamic viscosity is the newton-second per square meter (N·s/m2), also frequently expressed in the equivalent forms pascal-second (Pa·s) and kilogram per meter per second (kg·m−1·s−1). The CGS unit is the poise (P, or g·cm−1·s−1 = 0.1 Pa·s), named after Jean Léonard Marie Poiseuille.
Which is not a unit of viscosity?
Therefore Nm2/s2 is not the unit of dynamic Viscosity 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).
Which is a unit of viscosity?
What are the five common units of viscosity?
UNITS OF VISCOSITY.
Which is the SI unit of viscosity per second?
The SI unit of viscosity is the pascal second (Pa·s) or kg·m −1 ·s −1. The SI unit of kinematic viscosity is square meter per second or m 2 /s. CGS Unit of Viscosity
Who is the cgs unit of viscosity named after?
CGS Unit of Viscosity The cgs unit of viscosity is poise (P) and this name has been used in honour of a French physiologist Jean Léonard Marie Poiseuille. The cgs unit for kinematic viscosity is stokes (St) and has been named after Irish mathematician and physicist Sir George Gabriel Stokes.
How is the viscosity of a liquid related to its thickness?
We usually relate to the viscosity of a liquid by measuring the “thickness”. For example, we can state that honey is “thicker” (meaning a higher viscosity) than normal water.
How is the kinematic viscosity of a body measured?
Earlier, kinematic viscosity was measured using Saybolt viscometer where the units were expressed in Saybolt universal seconds (SUS). Other abbreviations such as SUV (Saybolt universal viscosity) or SSU (Saybolt seconds universal) are sometimes used.
