mass=density water*PI*radiustube^2 *height
force= masswater*g
I would also look at pressure, force/area
Placing a tube, with a radius of .30 cm, vertically into a barrel with a radius of 21 cm it was found that when the barrel was filled with water and the tube filled to 12 m the barrel burst. Calculate the mass of water in the tube and the net force exerted by the water in the barrel on the lid just before rupture.
