Literature review - Essay Example [ Gà ¡bor Takà ¡cs,2005] The concept would be to use a well of dimension 400x400x400mm, with a compressor attached to it and fitted with a foot valve. The user would press the footvalve to start the flow in the shower when required. This way the device lift will be activated by a start action and the device will remain in the lowered state until activated. The canister would be placed inside a cylinder (cubicle in this case) of dimensions 400cm x 400cm x400cm.The cubicle would extend to a height of 10 feet and is closed from the top to increase the pressure in the cylinder.[Michael] In his book, Water wells and Pumps, Michael describes various devices to lift water from wells. He describes the reciprocating pump as a pump having a piston or plunger working in a close-fitted cylinder. The movement of the piston/plunger displaces the water in the well and through the outlet. Reciprocating pumps can be either lift pumps that are designed to lift water to the spout , generally at a height of 2’-3’ from the ground or force pumps that are designed to lift water to greater heights from wells .This principle is used in supplying water to overhead tanks in domestic water supply. Because the top of the cylinder is closed in a force pump, water can be pumped to higher levels. In a single acting plunger type pump, the pump body consisting of the cylinder and plunger attached to a valve is located at ground level. The plunger when moved up and down by the movement of the pump rod displaces air through the cylinder through the non return valve at the bottom. On the downward stroke, the bottom valve closes and water passes through a second non return valve in the plunger. On the next upward stroke, this water is forced out of the spout. In a deep well lift pump, the principle of drawing water is the same, though it is pushed to a greater height
