Water Flow and PressureIn small groups complete these simple experiments to illustrate waterflow and pressure.Water Flow Measurement…Turn on a tap to see how long it takes to fill up a bucket. This will depend on how fast thetap is turned on – if turned on full it will take 10 – 15 seconds to fill up a 9 litre bucket.Estimate how many buckets of water would come out of the tap in 1 minute, 3 minutes and 10minutes.Water Pressure…Pressure is the force that pushes water through pipes. Water pressure determines the flowof water from the tap.You will need:♦ Plastic container♦ Ruler or tape measure♦ Bucket♦ Hose connect to water supplyAction:♦ Make a hole 3cm from the base of the container.♦ Place the plastic container on the upturned bucket on the grass♦ Turn the hose on and continually fill the container♦ Measure the distance the water spurts from the container♦ Turn the hose off and make 2 additional holes in the container, level with the first hole.♦ Repeat the filling and measuring exerciseObserve and record:♦ Discuss the results♦ What is the difference in distances with one hole then three holes?♦ How does it relate to the pressure in your taps?.18
