Chapter 12, Problem 4RC

Summary Introduction

Introduction: Viscosity is a function of the friction between the molecules of a fluid and is a determining factor of resistance in the movement of fluids. Poiseuille’s law explains the contribution of the length and the radius of the container through which the fluid is moving. Poiseuille’s law gives the following equation: ${\text{R=8Lη/πr}}^{\text{4}}$

In the above equation, $\eta$ represents fluid viscosity, L represents the length of the container, r represents the inner radius of the container, and $8/\pi$ is a mathematical constant.
