Hi all, I was trying to find the time required for liquid ejecting from a hole in a tank to reach ground level. The equation given in one of the books is as follows: t = √(2h/g) or sqrt of (2h/g). where h stands for the height of hole in tank shell from the ground level. This equation is true when the body is free falling with zero initial velocity. However, my question is whether the equation is valid when we are considering a liquid ejecting from the hole (which will definitely have initial velocity due to head of remaining liquid in the tank)? Thanks in advance.
