2.  Remember, fluids have no fixed shape and are free to flow. There are 2 types of flow:  Laminar Flow : › A smooth pattern of flow. Fluids move in orderly lines or along smooth pathways. › Allows fluids to move quickly with more energy

3.  Turbulent Flow : › An irregular, mixing flow pattern. › Different currents and pathways of fluids.

4.  Watch the videos and complete the following: › Identify laminar flow and turbulent flow › Real-life applications – How does an understanding of laminar and turbulent flow help us in real life situations? › Provide examples of laminar and turbulent flow with liquids.

5.  Flow Rate: › A measure of how quickly fluids move. › Measured in a volume per unit of time (for example, L/s).

6.  As Mr. Sebichon pours various liquids down a slope … › A volunteer will be in charge of the timer for each of the fluids. › Observe the characteristics of each fluid and determine why the different fluids flow at a different rate. › Another volunteer will be asked to describe the texture of each liquid. › Write your quantitative and qualitative observations in your chart.  Analysis: › Why do certain liquids have different flow rates? › Other than the liquid itself, can you think of any other reasons why the flow rate would be affected?

10.  Flow rate depends on several factors: › The type of fluid that is flowing (thin fluids vs. thick fluids) › The force pushing on the fluid (stronger forces vs. weaker forces) › The size of pipe or opening the fluid is flowing through (larger openings vs. smaller openings) › The type of surface over which the fluid is flowing (smooth surfaces vs. rough surfaces)
