Heh...this question actually looks as simple as hell (and it probably is)...but there always seems to be one variable missing:
A large storage tank, open at the top and filled with water, develops a small hole in its side at a point 16.0m below the water level. if the rate of flow from the leak is equal to 2.50 x 10^-3 m^3/min, determine (a) the speed at which the water leaves the hole and (b) the diameter of the hole.
I'm assuming that the storage tank is much bigger than the area of the hole, so the velocity of the water at the top is negligible...and the pressure there could be taken as atmospheric pressure (its open at the top). I could then use Bernoulli's equation but I seem to be missing the pressure at the point of leakage and I don't think that Pascal's equation would work due to the fluid retaining a velocity at that point.
