Viscosity 02
Viscosity 02 :
(F1 Mech) (1) The resistance of a fluid to flow. (2) The internal friction of a fluid. (3) The transport of momentum in a system due to a velocity gradient. See also: Boundary Layer. Note: Viscosity is defined as the force per unit area resisting the differential flow of two parallel layers of fluid a unit distance apart. the viscous force, in dynes, f = e • a(dv/dx), where e is the absolute viscosity coefficient in poise, a is the area in cm2, and dv/dx is the velocity gradient in cm-sec-1. for water at 20ºc, e = 10. 087 millipoise. for fluids in general, the coefficient of viscosity decreases with increase in temperature
