Flow Rate

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

A can of motor oil is spilt on a driveway. The oil travels 84 cm in 1 minute and 10 seconds. What is the flow rate of the motor oil?

Cooking oil with a flow rate of 2.6 cm/s flows down a tray for 15 seconds. How far down the tray would it have travelled in cm?

How many seconds would it take for a syrup with a flow rate of 0.75 cm/s to flow down a 60 cm long cookie sheet?

Two balloons are both filled with pure oxygen. One balloon is heated up while the other is cooled down. Which balloon would you expect to have the greatest flow rate of oxygen out of it if the balloon was released?

• The hotter balloon

• The cooler balloon

• They would both have the same flow rate
