so i was watchign a water fountain during a rally here today and was watchign the fountain in the middle and was wondering why (physically) when the water reaches the top it begins fallign in such a wide pattern. it makes sense to me intuitively but i don't know enough about physics to know just how it works. is it related to bernoulli's equation somehow? THat was my only thought when seeing it that maybe the spread of the water at the top can depend on the diameter of the pipe emitting the water and the pressure with which the water is pumped (and therefore the height it reaches) does any of that make sense? Am i even close to understanding just how this works? I guess that week off made my brain want to be used again so i'm pretty curious now. thanks!
