Chapter 7, Problem 7.8P

Interpretation Introduction

Interpretation: The value of temperature should be determined at which the kinematic viscosity of glycerin and helium is same.

Concept introduction: Viscosity / (Dynamic Viscosity) is defined as the property of fluid which offers resistance to fluid flow. It is denoted by $\mu$ .

Unit of viscosity is Ns/m².

Kinematic Viscosity is defined as the ratio of dynamic viscosity of fluid to density. It is denoted by $\vartheta$ . The unit of kinematic viscosity is m²/sec.

  $\vartheta =\frac{\mu }{\rho }$

Where,

  $\vartheta$ is kinematic viscosity having a unit of m²/sec.

  $\mu$ is dynamic viscosity having a unit of N.s/m².

  $\rho$ is density having a unit of kg/m³.
