But in this case we have to deal with the anisotropy of the viscosity, and in case of a liquid of the type of p-azoxyanisol we have three principal viscosity coefficients belonging to the three directions of orientation these are : (1) direction of the flow (2) direction of the velocity gradient (3) perpendicular to both these directions. If under the influence of any factor the molecules of the liquid should be orientated in one direction and the motion is unable to change this orientation, then we have the viscosity coefficient in the ordinary sense. For scattering in the triplet ground state a. Therefore this coefficient is a function of the velocity-gradient, and the usual definition of the viscosity coefficient for these liquids loses its significance. Coefficient of viscosity definition is - viscosity. This phenomenonis illustrated by wave function graphs and is discussed. length of the ship, is the dynamic viscosity of water and is the kinematic.
On the other hand, the value of the viscosity coefficient depends on this orientation. where Sh is the area of the hull and cp is the local coefficient.
Mathematically, Coefficient of viscosity () Fr/Av where F tangential force, r distance between the layers, v velocity. Kinematic Viscosity: The kinematic viscosity (v) is defined as the ratio of dynamic viscosity to mass density. Coefficient of viscosity is defined as tangential force required to maintain a unit velocity gradient between two parallel layers of liquid of unit area. As is well known, the flow of an anisotropic liquid influences the orientation of the molecules. (But note that the coefficient of viscosity is often measured in poise (P) 10 P 1 kg m-1 s-1.) Dimensions: ML-1 T-1. BEFORE and during the War, investigations were reported on the viscosity of anisotropic liquids 1,2,3,4.
