What is the purpose of an anemometer for kids?
An anemometer is an instrument that measures wind speed. It is usually made of several small cups attached to a vertical shaft. This is called a cup anemometer. As wind causes the cups and shaft to turn, the speed of turning can be used to calculate wind speed.
Are anemometers accurate?
Anemometer accuracy can vary greatly from device to device. Under normal conditions, a cup anemometer offers an accuracy ranging from 1% to 5%. But even lower values are possible with traceable specific calibrated instruments. In general we recommend always using a 1-2% accuracy sensor.
How do you make anemometer using materials found around you how will you use it?
Procedure:
- Use the hole punch to make a hole in the side of each of the 4 paper cups.
- Use the hole punch to make 4 holes spaced evenly around the rim of the last cup.
- Slide 2 of the wooden dowels through the holes in the center cup.
- Insert the ends of the dowels into the holes of the other cups and tape them into place.
What is anemometer made of?
They consist of a flat plate suspended from the top so that the wind deflects the plate. In 1450, the Italian art architect Leon Battista Alberti invented the first mechanical anemometer; in 1664 it was re-invented by Robert Hooke (who is often mistakenly considered the inventor of the first anemometer).
What is an anemometer used to measure?
An anemometer is an instrument used to measure the speed of the wind, which is a common weather station instrument or to calculate any form of current gas. The term is derived from the Greek word anemos meaning wind which was first explained by Leon Battista Alberti who was an Italian artist and an architect in the year 1450.
What is the difference between vane anemometer and hot wire anemometer?
The vane anemometer, thermal anemometer and cup anemometer (typically used in weather stations) are mostly used to measure the mean velocity, while the hot wire anemometers are usually used when turbulence characteristics are being measured, such as transverse measurements in a cross-section.
Can You mount a cup anemometer on a boat?
Most cup anemometers are meant to be mounted on either a building or a sailboat but there are some handheld cup anemometers that do exist. For more, see our article about the best cup anemometers and how cup anemometers work.
What is a handheld propeller anemometer?
Some handheld propeller anemometers are also called impeller wind monitors because their propeller blades are protected by a caging unit to make sure they don’t get caught on your hand. Some vane anemometers are meant to be mounted on buildings but handheld vane anemometers are also quite common.
