Viscosity and Fluids
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.
Connections to Fluid Properties
How does adhesion or cohesion impact the results of this experiment?
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.
Adhesion affects flow rate because it creates forces between the liquid and the surface it is flowing on. potentially slowing the flow.
