There are several different “types” of viscosities that one may encounter in fluid dynamics. First, we differentiate between the kinematic and dynamic viscosities, referred to by symbols ν and μ or η.They are related via the density of the medium, with ν = η∕ρ.The units of dynamic viscosity are Poise or Pa.s and the …

WebDynamic Viscosity Units Poise (symbol: P) Poise (symbol: P) Named after the French physician Jean Louis Marie Poiseuille (1799– 1869), this is the CGS unit of viscosity, equivalent to dyne-second per square centimetre. It is the viscosity of a fluid in which a tangential force of 1 dyne per square centimetre maintains a difference in velocity ... WebThe viscosity (or dynamic viscosity), symbol η, of a fluid is defined by the Newtonian equation τη= γ (1) where τ is the shear stress; η is the viscosity; γ is the velocity gradient dv/dz (v being the velocity of one plane relative to the other, and z the co-ordinate perpendicular to the two planes).
Informally, viscosity is the quantity that describes a fluid's resistance to flow. Fluids resist the relative motion of immersed objects through them as well as to the motion of layers with differing velocities within them. See more Viscosity is first and foremost a function of material. The viscosity of water at 20 °C is 1.0020 millipascal seconds (which is conveniently close to … See more The the mathematical expression describing the flow of fluids in circular tubes was determined by the French physician and physiologist Jean Poiseuille (1799–1869). Since … See more Motor oil is like every other fluid in that its viscosity varies with temperature and pressure. Since the conditions under which most automobiles will be operated can be anticipated, the behavior of motor oil can be specified … See more The mathematical expression describing the viscous drag force on a sphere was determined by the 19th century British physicist George Stokes.

The force necessary to move a plane of area A past another in a fluid is given by Equation 2.6.1 where V is the velocity of the liquid, Y is the separation between planes, and η is the dynamic viscosity. F = ηAV Y.
