I could be wrong but I vaguely remember in physics class, making a simple (text example) barometer which applies this principle?
The force of gravity at sea (ocean) level is equal to the height of the column of air (atmosphere) above it.
In the original post I had mentioned but deleted a question, 'you are going to buy a water pump, the first thing the salesman asks, Is it a deep well or shallow well?'
Why?
Have you ever tried to siphon gas from a tank? Let's see, you put a gas can on the trunk of the caar and extend a hose into the tank. Then you created a vacumn within the hose lifting the gas unti it starts to flow . Then sealing the end until you stick the hose into the can sitting on the trunk.
The vacumn formed will cause the gas to flow up the hose and into the can, correct?
