Utilizing the Components
If you do not have entry to a wind chill chart, you possibly can calculate wind chill utilizing the next method:
Wind Chill = 35.74 + 0.6215T - 35.75(V^0.16) + 0.4275T(V^0.16)
The place:
- T = Air temperature in levels Fahrenheit
- V = Wind pace in miles per hour
For instance, if the air temperature is 20°F and the wind pace is 15 mph, the wind chill could be calculated as follows:
Wind Chill = 35.74 + 0.6215(20) - 35.75(15^0.16) + 0.4275(20)(15^0.16)
Wind Chill = 35.74 + 12.43 - 35.75(2.14) + 0.4275(20)(2.14)
Wind Chill = 35.74 + 12.43 - 76.6 + 19
Wind Chill = 9.57°F
Components Affecting Wind Chill
Temperature:
The decrease the air temperature, the higher the wind chill. Even a slight wind can considerably improve the wind chill at chilly temperatures.
Wind Velocity:
The stronger the wind, the higher the wind chill. Excessive wind speeds speed up the speed of warmth loss out of your physique, inflicting you to really feel colder.
