Pressure and Flow: Using Water Tanks to Explain Why the Wind Blows
The wind blows because of pressure. Though it might not seem like it, observing the flow of water from one tank to another can help us understand how air moves in the atmosphere. This is because both water and air "flow" - which means they are both fluids! Use the simulation below to explore the movement of fluids through pressure and flow.
Consider these questions as you explore the water tank simulation above:
How do you get the water to flow from the tank on the left to the tank on the right? How does changing the initial height of the water in each tank affect both pressure and flow? How does the velocity of water change as it flows from one tank to another?
