Question

The wind chill factor represents the equivalent air temperature at a standard wind speed that would produce the same heat loss as the given temperature and wind speed. One formula for computing the equivalent temperature is
                           𝑡
W(t) = {33 − (10.45+10√𝑣−𝑣)(33−𝑡) / 2204
                    33 − 1.5958(33 − 𝑡)

if 0 ≤ v < 1.79
 if 1.79 ≤ v < 20
 if v ≥ 20

where v represents the wind speed (in meters per second) and t represents the air temperature . Compute the wind chill for an air temperature of 15°C and a wind speed of 12 meters per second. (Round the answer to one decimal place.) Show your work.
