I'm trying to understand Pascals principle in more detail so I made a drawing with a question to find out a segment of the differences between pressure and weight.
As demonstrated in the project "Pascals Barrel" the deeper depth of water the greater pressure on the lid of the barrel below would be. Here I've drawn a photo replacing the barrel to a simple type of hydraulic lift so that I can figure how much weight could be lifted and how much of a distance that it would be lifted upwards. It would help to figure out its equal equilibrium too.
To keep it simple please disregard any extra fluid or pipe in the drawing and just take the data that's provided below.
2" pipe that's 150 ft high = (24 gallons or 200 lb of water). Say this pipe is stagnant water. Because pressure and weight are of different things and assuming the fluid is now adding both the pressure and weight onto the piston below (at sea level) how much weight would that 24 gallons of water lift and how much of a distance would it be lifted? And or be at equilibrium?
That's 200 lb of fluid + the pressure it being in a skinny pipe reaching 150 feet in height.
