The last paper cup will form the center of the anemometer.By using the hole punch, make a hole on the side of each of the four paper cups.This will reveal how fast the wind is moving. The number of spins in a certain time interval is measured to calculate the speed of the wind.
The disposable cups are used to catch the wind that causes it to spin. The anemometer prepared this way is known as the Robinson Anemometer. Let us prepare an anemometer using disposable cups. An anemometer also employs laser and ultrasonic techniques to measure the wind accurately. Anemometers are of different types depending on the situation, ecosystems, and measurements. What is an anemometer method of construction? An anemometer can be easily constructed using a few basic materials. You can also count the number of times the cup rotates for 60 seconds to obtain the revolutions per minute directly. This way, the speed of wind is expressed in rpm. Multiply that number by two to obtain the value for rotations per minute or revolutions per minute. Then, you can count the number of times the cup moves to the front in 30 seconds.
What does an anemometer measure? If you want to measure the speed of the wind, you can take an anemometer outdoors. Even pocket-sized anemometers are available nowadays. Presently, modern anemometers are available that have a unique appearance. The measurement of the speed of the wind helps in forecasting weather like storms, hurricanes, and tornadoes. The revolutions in one minute give the wind speed in rpm units. The cups spin faster on their axis, depending on how fast the wind is. These four cups are linked to a horizontal arm. A traditional anemometer contains four cups to measure the speed of the wind. The wind causes the air to move, resulting in a difference in air pressure. What does an anemometer measure?Īnemometers are commonly found in weather stations.
They are also useful to physicists as they help them understand how the air moves. Anemometers are vital instruments for meteorologists as they help them to study weather patterns. What is an anemometer? An anemometer is a device used to measure the speed of the wind and its pressure.
