This is the principle that makes a waterfall work. Let’s assume that you were to hold a pipe vertically in the air. This pipe is 10 feet long. Now you hold your hand over the bottom end of the pipe to seal it. Then someone climbs up a ladder and fills the pipe with water. Taking our principle, let’s figure out how much pressure has built up. For every 2 feet of rise (or “head”), .87 pounds per square inch (PSI) of pressure will be formed. So 10 feet of rise (or head) will form 4.35 PSI.
