Refer to Table 8.5 on page 350 giving the heat index, I, in ◦F, as a function f(H, T) of the relative humidity, H, and the temperature, T , in ◦F. The heat index is a temperature which tells you how hot it feels as a result of the combination of humidity and temperature.
Answer the question in Problem9 for Boston in summer (H = 50, T = 80).
