Tube well
Tube well based on the principal that no space wants to remain vacant.
The opening through which water comes out from the lower gallon is closed and from the
opening of upper pipe of upper gallon water is filled in the upper and the lower gallon. After
filling the water the opening of the pipe attached to the upper gallon is closed. Again, when
the opening end of the lower gallon is made open then water from the upper gallon travels
towards the lower gallon and comes out from the opening end of the lower gallon.
The vacuum created in the upper gallon is filled up by water which comes from deep
down earth through the pipe already fixed for the purpose. Hence water from within the
earth keeps on coming and being drained out through the lower gallon.
Note:- The size of gallon and pipe has not been determined.
The Chak ball should be made in a way to enable to move up and down easily;
This can be used in draining to canal and pan in rivers like Ganga etc.
The volume of big gallon should be big and size of pipe should be big too.

abstract

To drain out water from tube well two gallons have been kept, one big and another small
big gallon. The big gallon will take water through the upper pipe set attached to it and will drain out through the small gallon.
