Do you ever wonder how fast that wind is going? 🌬️ Learn how to create a DIY anemometer and calculate the speed of wind with Alex Dainis. #DIY #Wind #Climate #Weather #Science | Museum of Science, Boston

Wind speed is typically measured using an anemometer, with common types including the cup anemometer, vane anemometer, hot-wire anemometer, ultrasonic anemometer, and Pitot tube. These instruments work by detecting the movement of air, either through mechanical rotation, changes in electrical resistance, sound wave travel times, or pressure differences. Wind speed is usually expressed in meters per second (m/s), kilometers per hour (km/h), miles per hour (mph), or knots. #windspeed #wind #scienc
