Chapter 3, Problem 149P
Consider the conditions of Example 3-14 in the text except that the ambient air is at a temperature of 30°C. A person with skin/fat layer thickness of 0.003 m is doing vigorous exercise which raises the metabolic heat generation rate from 700 to 7000 W/m3 over a period of time. Calculate the perspiration rate required in L/s so as to maintain the skin temperature at 34°C. Assume that perspiration properties are the same as those of liquid water at the average surface skimi temperature of 35.5°C.
