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

If you are planning to build a water wheel pump, the required materials for building it would be:wooden skewerflat pinsscissorssmall bucketwooden plankrulerstringcompassHope this helps.
it is a type of a wheel from which we pull water from the tube well.
a persian wheel is a thing which is consist of a number of bucket attached to a circular wheel
A rahat or Persian wheel is a type of water-lifting device that consists of a chain of pots attached to a wheel. As the wheel turns, the pots dip into a water source and bring water to the surface. It is commonly used in Iran and other parts of Asia for irrigation purposes.
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.
a persian wheel is a thing which is consist of a number of bucket attached to a circular wheel
The Persian wheel is a type of water-lifting device used to irrigate fields. It consists of a set of buckets attached to an endless chain, which turns as it is rotated by an animal or engine. As the buckets move, they collect water from a well or river and then dump it into a trough, which directs the water to the fields for irrigation.
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?
A turbine or water wheel,
