rahat is a traditional method of irrigation in which animals like oxen is used to pull out water from the wells. This water is then evenly spread out over the fields. It is cheap but not very efficient method of irrigationPosted by guptaindustries39...(student), on 30/5/12

The water wheel has been around for ages, and have been invented several times in historu, and in different places. No single inventor can be pinpointed.
it is a type of a wheel from which we pull water from the tube well.
It is used to lift water from water sources typically open wells.
a persian wheel is a thing which is consist of a number of bucket attached to a circular wheel
Water can supply electricity in usually one reason - the water wheel, or it's close cousins. The water pushes on the wheel, and turns the water wheel. As the wheel spins, it creates mechanical energy. This mechanical energy is fed through a converter, which turns it into useable electricity. It is the same concept as wind with a wind turbine.

Depending upon type of well it may be Persian wheel , pully and bucket , etc.
It was called the Sakia and sometimes called the Persian wheel which is a water wheel, and used primarily in Egypt. It is a large hollow wheel, normally made of galvanized sheet steel, with scoops or buckets at the periphery. Its unique characteristic is that water is dispensed near the hub rather than from the top. It is a method of irrigation frequently met within various parts of India. We really can't know who was the first to make one but the Greeks have some of the oldest water wheels found.
I don't know I need to know that too. :/
Explain how the mechanical advantage of a wheel and axle change as the size of the wheel increases?
Before the god created the earth you sun of freak
the more force that the water has on the wheel the more work the water wheel do
