Wind Chill Temperature 3574 06215T - 3575V 016 04275TV 016 where T is the actual air temperature in fahrenheit V is the wind speed in mph. You may plot your results in a separate window by clicking on Plot in the appropriate column. To calculate wind chill factor it requires an anemometer an instrument for measuring the speed of the wind and a thermometer.
For example if the wind speed is 70 mph the wind stagnation pressure is 000256 x 70 2 125 psf.
This calculator uses the formula developed by the National Weather Service in the United States which was listed below. Multiply the number of rotations by the diameter of the anemometer in inches and divide by 168. 100 mph x 5280 feet 528000 feet per. Calculate a miles per hour wind speed in feet per hour then divide by the number of feet in a knot.
