Chapter 15, Problem 79RPP

To determine

The rate of the quantities provided in the table that will change when a person runs outside on a windy day, from the following options:

a. The work done by the drag force might increase because wind can exert a greater force than stationary air.

b. Cooling by evaporation might increase because the wind will spend up the evaporation process.

c. Cooling by convection might increase in the same way as with forced convection.

d. Cooling by radiation might increase because the temperature of skin surface will decrease.

e. All of the above

f. (a)-(c) are correct, but not (d).
