Wind Chill 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 ( 10.45 + 10VV - v) (33 - t) W = 33 - 22.04 33 - 1 .5958(33 - t) O:s V < 1.79 1.79 :S v :S 20 v > 20 where v represents the wind speed (in meters per second) and t represents the air temperature (0C). Compute the wind chill for the following: (a) An air temperature of 10C and a wind speed of 1 meter per second (m/sec) (b) An air temperature of 10C and a wind speed of 5 m/sec (c) An air temperature of lOoC and a wind speed of 15 m/sec (d) An air temperature of lOoC and a wind speed of 25 m/sec (e) Explain the physical meaning of the equation corresponding to 0 :S V < 1.79. (f) Explain the physical meaning of the equation corresponding to v > 20.
