/diy/ - Do It Yourself

First off, I know that the numbers aren't accurate, but getting accurate numbers is too much effort to add nothing to the concept.

So this system where you funnel 100lbs of water down from 10x10in to 1x1in should theoretically raise the water pressure to 100psi. But it doesn't. Why not? I know I'm dumb for asking this but there's no stupid questions. So what's missing to make this not work?

I'm trying to design something to use just the weight of water and gravity to increase water pressure, without electricity or anything, so if there's any ways to do that, please tell me
