Draw a diagram to show pumping of underground water using wind energy.

A water pumping windmill is simple, and efficient. The blades of the windmill wheel catch the wind, which turns the rotor. ... This motion drives a pump rod, up and down inside of a pipe in the well. A cylinder with a sealed plunger going up and down inside forces the water up the pipe.Wind turbines operate on a simple principle. The energy in the wind turns two or three propeller-like blades around a rotor. The rotor is connected to the main shaft, which spins a generator to create electricity. Click NEXT to learn more.

The latest windmill the  windmill can raise water from as deep as 250 feet in the ground. This is a far greater pumping capacity than any other low-cost machine can offer, and in fact, matches the lifting ability of very expensive, commercially made units. The wind mill works on the principle of converting Kinetic energy of the wind to mechanical energy. We know that power is equal to energy per unit time. The energy available is the kinetic energy of the wind. The kinetic energy of any particle is equal to one half its mass times the square of its velocity.
