Segment V1.1: Viscous Fluids

(Related to Textbook Section 1.6 - Viscosity)

The behavior of a flowing fluid depends on various fluid properties. Viscosity, one of the important properties, is responsible for the shear force produced in a moving fluid.

Although the two fluids shown look alike (both are clear liquids and have a specific gravity of 1), they behave very differently when set into motion. The very viscous silicone oil is approximately 10,000 times more viscous than the water.
