Asked by Yew Florence

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.
Answered by bobpursley
mass=density water*PI*radiustube^2 *height

force= masswater*g

I would also look at pressure, force/area
