Exercise 11

Explain what the wind chill index is relative to convective heat loss.

Step 1 of 3

Wind is movement of atmospheric air. The speed of wind influences the rate of heat loss from the body. Wind increases the number of cold air molecules that come in contact with the skin so that heat loss is accelerated. The more is the velocity of wind, the more are the cold air particles that hit the skin per unit time and more is the heat loss.
