Homework Statement
When you look at the manual hand pump, you would push down on a lever and a piston would rise creating a vacuum in the chamber. which would bring the water upward because of atmospheric pressure push the water upward.
Now I have two questions about this.
My first question is if the water supply is at a level of 32 feet downward and the water was brought up to the vacuum chamber, and with one push upward on the piston inside the pump. Would that create enough vacuum force to pull the water upward, or would the weight of the water create too much pressure that the atmospheric pressure can't push it upward? keeping in mind that the pump creates a low vacuum and atmospheric pressure is 14.7 psi and the water pressure downward is around 13psi.
My second question is what actually happens in the water that is in the pipe going up to the pump? Does the water decrease in density when there is a drop in pressure in the pump.
