Wind Energy
Wind is an indirect source of solar energy. It is caused by the uneven heating of the earth by the sun and the resulting redistribution of air to equalize energy in the atmosphere moving air from areas of high pressure to areas of lower pressure. The energy of the wind is transferred to the windmill's sails where it is harnessed to perform work.
The cap of the windmill is turned with the winch attached to the bottom of the tail pole until the sails face the direction of the wind. Depending on the wind speed, wind boards are installed on the leading edge of the sails and canvas sail-cloths are unfurled across the sail-frames. The Miller climbs the sail-frame using the sail-bars like rungs of a ladder attaching the canvas to the cleats on the whip. High winds require less open sail than low wind. The Miller determines the amount of sail surface required based on wind speed and partially furls (reefs) the sails as required. The sails catch the wind and turn the wind-shaft.
The wind-shaft which is connected to the brake-wheel can be stopped with the brake which consists of a band of friction blocks encircling the brake-wheel attached to the brake lever and controlled via a rope near the tail pole attached to the brake lever. The turning brake-wheel turns the wallower connected to the upright shaft on the fifth level. A wood wheel on the fourth level is used to adjust any irregular spinning of the upright shaft.
The upright shaft is connected to a large gear called the spur-wheel on the third level. Power to run many things in the windmill is drawn from this wheel. Two stone-nuts turned by the spur-wheel drive quant shafts in turn rotating the runner stones; the top stones of the grinding stone pairs. The lower stone of the grinder is the bedstone; it remains stationary. The spur-wheel also turns a third lantern gear (trundle) to drive power transfer belts, pulleys and shafts used to operate the grain elevators, sifters, grain separator, corn sheller and a vacuum system.
Wind mill is one type of machine. It is convert wind energy in to mechanical energy.
Ceiliog gwynt is wind vane.
I used a wind vane to see what direction was the wind blowing to
Weather vane or wind vane does not measure anything, it just shows the direction the wind is out of, a wind monitor measures the force the wind is blowing, in mph or kph.
It is measured using an anemometer.
There are some things to know about wind vanes. Don't get the wind vane confused with an anemometer because the anemometer measures wind speed. Though they are both used to the wind they have different functions. The wind vane is used for the wind direction, however, the wind vane is also called the weather vane.
Wind vane
Weather vane is for direction and anemometer is for speed
A wind vane measures the direction of the wind.
Ceiliog gwynt is wind vane.
The weather vane, also known as the wind vane, tells you which direction the wind is blowing.
No. A wind vane is an instrument that can tell wind speed but not wind direction.
The wind vane is in the barn.
I used a wind vane to see what direction was the wind blowing to
No a wind vane measures or indicates wind direction.
An Anemometer measures the wind speed and the Wind Vane measures the direction of the wind.
Weather vane or wind vane does not measure anything, it just shows the direction the wind is out of, a wind monitor measures the force the wind is blowing, in mph or kph.
