Hi everyone. My dad was debating with his friends over something, and he asked me for my opinion too. I've been on these forums before so I thought I'd ask here.
So let's say you have two pipes. Both have the same cross-sectional area, same fluid inside, and they both extend to the same height at the top. However, one is straight and one curves around a bunch like a snake. If we stick a pressure gauge at the bottom of both, will the readings be the same?
It's been years since I've taken physics, but I remember the formula for pressure in this case was like density*gravity*height. In that case, wouldn't it be the same for both pipes unless you count the whole length of the curved one? Even though his friends argued that way, it just doesn't seem right. I'm guessing there's some more complicated stuff involved besides just that simple equation.
