Use an anemometer, a device that turns when the wind blows against it. If properly calibrated, the rate of turning will tell you how fast the wind is blowing.
It measures wind pressure
wind velocity
An anemometer measures wind velocity.
The reason the anemometer is so important is because you use it to measure the velocity of the wind and to measure pressure of the wind ----
because wind has speed, motion, it accelerate, which is measured in velosity.
Depends on what you mean by observation. There are instruments that measure wind velocity, There are wind socks that show if the wind is blowing and what direction.
Generally wind speed is measured using a cup anemometer (wind speed measuring device). The velocity of a flatulation will decrease as it leaves the anus, so to properly measure the velocity the measurement would have to be done before the exit. Theoretically you could measure the velocity of the gases by placing a miniature cup anemometer with walls inside the rectal tract close to the anus to give an approximate wind speed (velocity) of the gases.
An anemometer is used to measure
The Beaufort scale is an empirical measure for describing wind velocity based mainly on observed sea conditions.
Measure the rpm & calculate the torque as power divided by angular velocity
A device used to measure wind speed. It is mostly used by meterologists and weather forecasters.
An anemometer is used for weather forecasting by meterologists . Aeroplane pilots and sailors need to know the velocity of wind . Therefore they use anemometers to fullfilltis needfor wind speedan anemometer is used to measure wind speedAn Anemometer is a device for measuring wind speed. They are common in Weather Stations.
