Title says it all. And I’m not talking about cloudy water. Just the stream itself looks white when it gets to a certain speed. When it settles in a cup it looks the same. Does it bubble when it moves or something? Why would there be bubbles from the faucet? I just don’t get it. (‘:
In: Physics
Faucets usually have aerators, which reduce both water consumption, splashing, noise, random directions, etc by adding air to the running water. Slower flow rates reduce the efficiency of this process by allowing less aeration and more debubbling of the air that did get in. Why does it look white? That’s just light refraction and scattering due to the many interfaces it encounters between air and water in the flowing column.
