Today, we continue our exploration of fluids and fluid dynamics. How do fluids act when they're in motion? How does pressure in different places change water flow? And what is one of the motion annoying things about filming outside on a nice day? I'll give you a hint on that last one... it's lawnmowers.

In this episode of Crash Course Physics, Shini talks to us about how fluids in motion are really, really, REALLY powerful things.

THE HIGHER A FLUID'S VELOCITY IS THROUGH A PIPE, THE LOWER THE PRESSURE ON THE PIPE'S WALLS, AND VICE VERSA

TORRICELLI'S THEOREM
/youtube/video/fJefjG3xhW0?t=403
THE VELOCITY OF THE FLUID COMING OUT OF THE SPOUT IS THE SAME AS THE VELOCITY OF A SINGLE DROPLET OF FLUID THAT FALLS FROM THE HEIGHT OF THE SURFACE OF THE FLUID IN THE CONTAINER.
