Homework Help: Physics Question

Posted by Catherine on Saturday, May 7, 2011 at 11:35pm.

Here is a demonstration Pascal used to show the importance of a fluid's pressure on the fluid's depth : An oak barrel with a lid of area 0.17 m^2 is filled with water. Along, thin tube of cross-sectional area 4.710−5 m^2 is inserted into a hole at the center of the lid, and water is poured into the tube. When the water reaches 12 m high, the barrel bursts.

What was the pressure of the water on the lid of the barrel?

What was the net force on the lid due to the water pressure?
