Question 179175
determine who will feel colder: a person in Minneapolis at 10 degrees F with a 15 mph wind or a person in Chicago at 20 degrees F with a 25 mph wind.
The formula:
W = 91.4-{{{((10.5+6.7*sqrt(v)-0.45v)(457-5t))/110}}}
:
Minneapolis: t=10, v=15
W = 91.4-{{{((10.5+6.7*sqrt(15)-0.45(15))(457-5(10)))/110}}}
:
W = 91.4-{{{((10.5+(6.7*3.873)- 6.75)(457-50))/110}}} 
:
W = 91.4-{{{((10.5 + 25.95 - 6.75)(407))/110}}}
:
W = 91.4-{{{((29.7)(407))/110}}}
:
W = 91.4-{{{(12087.9)/110}}}
:
W = 91.4 - 109.89
:
W = -18.5 degrees wind chill 
:
:
Chicago: t=20, v=25
W = 91.4-{{{((10.5+6.7*sqrt(25)-0.45(25))(457-5(20)))/110}}}
:
W = 91.4-{{{((10.5+(6.7*5)-11.25 )(457-100))/110}}} 
:
W = 91.4-{{{((10.5 + 33.5 - 11.25)(357))/110}}}
:
W = 91.4-{{{((32.75)(357))/110}}}
:
W = 91.4-{{{(11691.75)/110}}}
:
W = 91.4 - 106.29
:
W = -14.88 degrees wind chill

It's a little colder in Minneapolis, but I doubt if one could notice it
