how to calculate wind speed with an anemometer

However, meteorologists use many other tools to determine what the weather will be like. I used a hand held wind speed device to calibrate my Arduino code.. I’m using pinMode (2, INPUT_PULLUP); so no pull up or pull down resistor is needed. anemometer to spin. Multiply the number of rotations by the diameter of the anemometer in inches and divide by 168. Wind Speed We can measure the wind speed by using equipment called "Anemometer". Newbie; Posts: 21; Karma: 0 ; Re: code to record wind speed #2 May 07, 2018, 10:39 am. In these ... preferably MKS.   Cup anemometers feature a rotating array of wind cups that rotate as the wind blows. 4 plastic drinking straws it spins easily. Instantaneous Wind Speed = Anemometer Factor x Instantaneous Shaft Speed; Average Wind Speed = Anemometer Factor x (Number of Turns / Time) The sampling frequency of an anemometer describes how often the unit takes a wind speed measurement. In short, anemometer measures velocity of the wind. Divide the into small groups with the following roles (optional). Staple the top side of one drinking cup, such as the small paper cups designed for bathroom dispensers, to the end of each straw, so the open : BTMeter Wind Speed Measuring Anemometer. A cup anemometer has a vertical pole with three cups that capture the wind. fourth grade class in Garfield, New Jersey making their anemometers. Arrange four (4) plastic drinking straws to form a cross and tape them A value of 0.4V represents no wind and 2V represents a wind speed of 32.4 m/s. useful to use a commercial anemometer to determine an approximate PaulRB. Center for Innovation in Engineering and Science Education (CIESE) All Rights Reserved. To calculate the wind speed, one has to measure the number of spins in a given time interval. the speed of the wind? many times the marked cup passes them in one minute and write it down. Then, they add a motor to their model to simulate wind speeds around the world using a customized Excel workbook. The angular velocity describes the speed at which a circle is spinning. For example, an anemometer with a frequency of 0.1 Hz counts the number of turns over a 10-second period to provide a speed value. This anemometer has four cups which catch the wind and cause the As we know air travels high-pressure places to low-pressure places, this movement creates wind. Anemometer is a scientific device which is used not only to measure the speed of the flowing wind but also to know the direction of the moving wind. Arrange four (4) plastic drinking straws to form a cross and tape them The number of turns per second can be used to calculate wind speed, and modern electronic anemometers can do this automatically. Includes templates, a list of things you need and detailed instructions. One official "counter" for the day. Mount or hold the anemometer in a place that has full access to the wind but the counter's readings will be the ones recorded. Procedure Multiply this number times the number of revolutions per minute to get the number of feet per minute (fpm) one scoop travels. We use an instrument called an anemometer to measure wind speed. It gives a direct measure of the speed of the wind. many times the marked cup passes them in one minute and write it down. That's what makes the cups move. Students and teachers are eligible for free Office 365 Education, which includes online Word, Excel, PowerPoint, and OneNote. NOTE: When using this anemometer, 10 turns per minute Optional: you can multiply the average number of spins by 60 to find Mark one of the cups; this will be the one they use for counting when is unobstructed. The inward curve of the cups receives most of the force 3. determination. Materials Hotwire anemometers measure both wind speed and pressure. The more spins per minute, the Push a straight pin through the center of the straws into an eraser on Anemometer (above) Some people think wind turbines areunsafe because gales and storms could make themspin dangerously fast. There you hav… Copyright � 2007 Stevens Institute of Technology, Costs approximately $2.00 to 5.00 USD per student, excluding tools and microcontroller, Meets middle school science, technology, engineering and math standards (STEM). An anemometer is a tool used to calculate wind speed. display the wind speed in miles per hour (mph) or kilometers per hour (kph This type of anemometer is commonly seen on weather stations and is often used in our weather reports on the news. 2.
