Flow Rate and Viscosity

What is flow rate?

• Is the measure of the velocity of fluid movement; measured in volume per unit of time

  (For example L/S)

• When different molecules attract to each other because of fluid movement

• The degree in which particles of a fluid are measured by how they are attracted to one another

• The attraction between particles of the same substance and particles of other substances

Fluids with high _________ such as honey pour slowly.

What is viscosity?

• A measure of how easily a fluids particles are able to slide past one another.

• Usually measured by how strongly particles of a fluid attract to each other

• When the strong attraction between the particles that form the surface of a liquid.

• The attraction between the particles of one substance and the particles of another substance

What is the relationship between flow rate and viscosity?

• Viscosity increases and the flow rate decreases

• The flow rate increases and viscosity decreases.

What is a sticky note an example of?

• Viscosity

• Cohesion

• Surface tension

• Adhesion

What are TWO of the several factors of flow rate?

• 2. the tension that is applied to the fluid to give it a high viscosity rating

• 1. depends on the fluid that is flowing

• 2. Depends on the weight of the water, and how it's measured

• 2. the force pushing on the fluid

Write the other 2 according to your memory.

Which one is it?

What causes fluids to flow more easily than others?

• Flow rate

• Adhesion

• Cohesion

• Suface tension

• Viscosity

Cohesion: a measure of how strongly the _________ of a fluid attract each other.

Surface tension: the strong __________ among the particles that form the surface of a liquid.
