How far up can a pump lift water, and why is the discharge side
smaller than the suction side of the pump.

The highest a suction pump can lift water is the height of a column of water that can be supported by atmospheric pressure; about 10 metres or 32 feet. It's the air pressure pushing down on the water surrounding the intake that pushes the water up. You've got a near-vacuum at the top of the column, produced by the suction pump. The suction side is wider because, if there's anything on the suction side of the pump to reduce the vacuum, like a pinhole leak, too much drag caused by a narrow intake or a grain of sand in the cylinder, your pump won't suck the water high enough. Our suction pump has to suck water up from the bottom of a 9-metre bore, and it's always giving trouble. A submersible pump at the bottom of the bore that pushes water up has no theoretical limit. It's more expensive but gives less trouble.

depends on your pump. it is smaller because more pressure can be exerted through the smaller side thus giving it more thrust. also not all pumps use this way of pumping! some use Impellers 1 to 15 and it depends on these centrifugal effect impellers or the arcimedial effect impellers that give the thrust for the water to be lifted as it were if there is no pump then water can only rise to sea level if you live below sea level due to atmospheric pressure

Regardless of the power of the pump, water cannot be lifted more than the equivalent of one atmosphere of pressure, about 33-34 feet.

It depends on the pressure the pump can exert. I slept through the physics lecture, but it has to do with the pressure at both ends being the same 1 ATM or something like that.

Depends on the power of a pump, look at oil pumps. residue is the small scale of dirt or residue on the dirt or rocks in the process. What location you asking about? New drilling areas will get much more garbage at first, depending on the part of the earth you are asking about. Ron Couch
