Literature review - Essay Example Gbor Takcs,2005The excogitation would be to use a well of dimension 400x400x400mm, with a compressor attached to it and fitted with a foot valve. The drug 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 lower state until activated. The canister would be placed inside a cylinder ( prison cell in this case) of dimensions 400cm x 400cm x400cm.The cubicle would extend to a height of 10 feet and is unsympathetic from the top to increase the pressure in the cylinder.MichaelIn his book, Water wells and Pumps, Michael describes various devices to lift body of water system from wells. He describes the reciprocating marrow as a ticker 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 th at 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 utilize 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 back end. 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
