Question 181308: A column of water 2.31 feet high exerts a pressure of one (1) pound per square inch. How much pressure does a column of water 46.20 feet high exert?
--- I figured out that are are 27.72in in 2.31 feet. So I thought that meant there were 27.72 pounds of pressure. But because it is square inches I was questioning whether or not that was correct, therefore I did not go on to figure out the rest of the problem. Your help would be greatly appreciated!

You can put this solution on YOUR website! A column of water 2.31 feet high exerts a pressure of one (1) pound per square inch. How much pressure does a column of water 46.20 feet high exert?
------------------
Each 2.31 ft exerts 1 psi. So 4.62 feet would be 2 psi.
psi = feet of column/2.31
psi = 46.2/2.31 = 20
46.2' exerts 20 psi
--------------
The pressure, in psi, is the depth (in feet) divided by 2.31.
