Flow Rate and Density

How is flow rate caluclated?

• Flow rate equation is L/s

• Flow rate equation is s/L

• Flow rate equation is L x s

• Flow rate equation is s x L

What factors does flow rate depend on?

• The opening the fluid is flowing through

• The smell of the fluid

• The colour of the fluid

• The temperature of the fluid

What type of fluids tend to flow faster than others?

• thin fluids

• scented fluids

• thick fluids

• colourless fluids

What does viscosity refer to in a fluid?

• colour

• temperature

• resistance to flow

• smell

What is cohesion in relation to fluid flow?

• The force of gravity on fluids

• The force of attraction between particles of a fluid and particles of other substances

• The resistance to flow

• The force of tension between the particles of a substance

What is adhesion in a fluid?

• The force of tension between particles of substances

• The force of attraction between particles of a fluid

• The resistance to flow in fluids

• The curved surface of a meniscus

What fluid has the least viscosity?

• thick fluids

• gases

• colourless fluids

• thin fluids

What is responsible for the curved top surface when water touches the sides of a cup (the meniscus)?

• surface tension

• cohesion

• adhesion

• viscosity

Which fluid particles have greater cohesion?

• particles that stick together

• particles with less viscosity

• particles in gases

• particles in thin fluids

Which factor does NOT affect flow rate?

• force pushing on the fluid

• adhesion

• size of the pipe

• type of fluid
