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
π‘
W(t) = {33 β (10.45+10βπ£βπ£)(33βπ‘) / 2204
33 β 1.5958(33 β π‘)
if 0 β€ v < 1.79
if 1.79 β€ v < 20
if v β₯ 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 15Β°C and a wind speed of 12 meters per second. (Round the answer to one decimal place.) Show your work.
