hi
We all know when velocity of fluid increases then cross section decreases for same mass flow rate and this can be well seen at water flowing from a height as in waterfalls.
But why this doesn't happen when water flows down through a vertical held pipe of constant cross section. Well you may say that since cross section of pipe is constant so it's velocity will remain same but why then velocity doesn't increase due to gravity?
