PPT-Viscosity Introduction

Viscosity is a quantitative measure of a fluids resistance to flow Dynamic or Absolute Viscosity The dynamic viscosity η of a fluid is a measure of the resistance it offers to relative shearing motion. (2.2)PHYSICAL PROPERTY. A physical property is any characteristic of a material that can be observed or measured without changing the composition of the substances in the material. . Viscosity, conductivity, malleability, hardness, melting point, boiling point, and density are examples of physical properties.. : Lecture 11. (ME EN 7960-003). Prof.. Rob Stoll.

The red dots show the location of active volcanism. Notice how the majority of the volcanism is focused in lines along the plate boundaries? For this region is the area known as the “Pacific Ring of Fire”..
