Flow Rate

​ (a)   is a measure of how quickly a liquid flows

• flow rate
• viscosity
• fluid
• density
• temperature

Factors that affect the control of fluids are:

• size of the opening the fluid is flowing out of

• the type of fluid that is flowing

• the opaqueness of the fluid

• amount of force exerted on the fluid

• the type of surface the fluid is flowing over

The study of fluids and how they behave when at rest and moving.

• Fluid Dynamics
• Fluid Analysis
• Fluid Studies
• Fluid Mechanics

The study of the behaviour of fluids when moving.

• Fluid mechanics
• Fluid dynamics
• Fluid engineering
• Fluid analysis

What is the formula to calculate flow rate?

• Flow Rate = Volume / Time
• Flow Rate = Volume x Time

• Flow Rate = Time / Volume
• Flow Rate = Distance / Time

A fluid travels a distance of 4.5 cm in 3 seconds. Calculate the flow rate of this fluid in cm/s.

A bottle of syrup is poured down a 50 cm tray. If it takes the syrup 40 seconds to flow all the way down the tray, then what is the syrups flow rate (cm/s)?

If the tray was cooled down, how would this affect the syrup's flow rate?

• It would go up

• It would go down

• It would not change
