Chapter 4, Problem 4.3P

Select comfortable summer design conditions (dry bulb and relative humidity) for a machine shop where people in light clothing $\text{(clo=0}\text{.5)}$ will be engaged in active work such as hammering, sawing, and walking around $\left(\text{met = 1}\text{.8}\right)$. Begin by selecting an operative temperature from Fig. 4-1. Assume that the mean radiant temperature is equal to the dry bulb temperature. A supervisor who is much less active than the other workers will occupy a space in the same environment. What is your suggestion for maintaining his or her comfort?
