It depends on the pressure and the time frame. A billion gallons, if you wait long enough.
This can vary with the local water pressure. It decreases with pipe length and building elevation.
None with out pressure
question cannot be answered because it depends on the water pressure
Given enough time the entire ocean could be pumped through a half-inch pipe.

Gravel doesn't fit close together like clay soil particles do, slowing down water flow through mud. If you visualize gravel as a screen of 1/8th inch mesh and clay soil as a screen of 1/128th mesh ( 16 times smaller holes ) you can then easily understand that water flows very swiftly through the gravel screen compared to the fine particles of clay soils.
Depends on the pressure. What bar do you intend to run at?
An inch of rain implies water one inch deep per surface area. An inch of rain equals 5.61 gallons per yard. An inch of rain equals 27,150 gallons per acre.
Given long enough, all the water in the world.
48 feet per hour=48x12 inch per hour=48x12/60 inch per min=9.6 inch per min
Depends on the diameter of the pipe and the speed at which the water travels through it.

You can convert a deep well jet pump to a shallow well jet pump by plugging the top three quarter inch opening, and drawing water in through the bottom one and a quarter inch opening.
