Abstract
VISCOSITY IS A PHENOMENON WHICH IS OF GREAT IMPORTANCE TO THE THEORY OF FLUID MECHANICS AND KEY TO UNDERSTANDING MANY PHENOMENA IN NATURE. USING THE FORMALISM AND METHODS OF STATISTICAL MECHANICS, WE HAVE COMPLETED AN INTUITIVE DERIVATION OF VISCOUS SHEAR STRESS IN A FLUID BY CONSIDERING MOMEN TUM TRANSPORT OF PARTICLES CONSTITUTING SAID FLUID AND OBTAINED AN EXPRESSION FOR DYNAMIC VISCOSITY WHICH DEPENDS ON PARTICLE PROPERTIES AND STATE VARIABLES. WE COMPARE THEORETICA L PREDICTIONS MADE BY THE MODEL WITH EXPERIMENTAL DATA.
