The Wind-Chill Index I Is the Perceived Temperature When the Actual

Short Answer

The wind-chill index I is the perceived temperature when the actual temperature is T and the wind speed is v so we can write $I = f ( T , v )$ . The following table of values is an excerpt from a table compiled by the National Atmospheric and Oceanic Administration. Use the table to find a linear approximation $L ( T , v )$ to the wind chill index function when T is near $16 ^ { \circ } \mathrm { C }$ and v is near 30 kmh.
