Figurativly I have a 33 gallon barrel and it has a one inch hole in the bottom, if the barrel is full of water, how many gallons would escape a minute, the top is open, I need to know to figure out how much water being pumped in would...

    Absorbed into a new dynamic flow

To ponder a wisdom expounded as fact, and to fully believe in it, we have excluded probability of contagious thought, we then fail to see as a child...

    Whirlpool in a barrel

    Siphon acceleration or equilibrium?

    If I had a barrel of water on a pedistool, and at the bottom of the barrel there is a siphon, that would pump out, my question is, whether the rate of water that would normally flow from the barrel following down the path of least resistance, would the syphon be able to increase the volume and...
