Question

the air temprature is -10c. With the wind blowing at a speed of 15km/h, this temperature feels like -17C. How many degrees does the temperature change because of the wind chill?

Answer 1

The wind chill factor, which represents how much colder the air feels due to the wind, can be calculated using a formula. The formula for calculating wind chill is:

Wind Chill (°C) = 13.12 + 0.6215 * T - 11.37 * V^0.16 + 0.3965 * T * V^0.16

Where:

T is the actual air temperature in Celsius (in this case, -10°C).

V is the wind speed in km/h (in this case, 15 km/h).

Now, let's calculate the wind chill:

Wind Chill = 13.12 + 0.6215 * (-10) - 11.37 * (15^0.16) + 0.3965 * (-10) * (15^0.16)

Wind Chill ≈ 13.12 - 6.215 - 11.37 * 1.9306 - 5.963

Wind Chill ≈ 13.12 - 6.215 - 21.993 - 5.963

Wind Chill ≈ -20.065°C

So, the temperature change because of the wind chill is approximately 7 degrees Celsius. The air temperature of -10°C feels like -17°C due to the wind chill factor.
