Viscosity and Fluids

What is viscosity?

What is viscosity? Write a definition in your own words.

viscosity is the resistance to flow of a fluid.

Flow Rates

What were the results of each fluid? Water, cooking oil, honey, syrup.

W: 0.103 ml per second

H:57.9

CO: 0.204

S:1.41

Factors Affecting Flow

What factors affected flow in our experiment? Think about the funnel, opening of the funnel, and equipment used to conduct this experiment.

Connections to Fluid Properties

How does adhesion or cohesion impact the results of this experiment?

Adhesion affects flow rate because it creates forces between the liquid and the surface it is flowing on. potentially slowing the flow.

Cohesion is the force between molecules within the same liquid. Cohesive forces are responsible for surface tension. High cohesion means higher surface tension, which can increase flow resistance and decrease flow rate.

Real World Applications

Where would it be important to understand viscosity or flow rate in real life?

Cosmetics and Personal Care Products: The viscosity of products like shampoos, lotions, and toothpaste affects their application, spreadability, and overall user experience. Manufacturers carefully control viscosity to get the desired flow and texture properties.
