WebDynamic 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. It is more commonly expressed, particularly in ASTM standards, as centipoise (cP). WebUnits for Dynamic Viscosity. The most commonly used unit for dynamic viscosity is the CGS unit centipoise (cP), which is equivalent to 0.01 Poise (P). This unit is used in honor of French physicist, Jean Léonard Marie Poiseuille (1797-1869), who worked with Gotthilf Hagen on the widely known Hagen-Poiseuille law which applies to laminar flow ...

WebDynamic viscosity. The IUPAC symbol for viscosity is the Greek symbol eta (η), and dynamic viscosity is also commonly referred to using the Greek symbol mu (μ). The SI physical unit of dynamic viscosity is the pascal-second (Pa·s), which is identical to 1 kg·m −1 ·s −1. If a fluid with a viscosity of one Pa·s is placed between two ... WebJun 6, 2011 · n air = 17.4e-6 Pa.s. density water = 1000 kgm^-3. density air = 1.3 kgm^3. and kinematic viscosity v = n/density. So v air ~ 1.4e-5. v water ~ 1e-6. So here the dynamic viscosity of water is greater than that of air, but the kinematic viscosity for water is less that that of air.
