(50 pts). Refer to the psychometric chart on the next page, and the following meteorological data. The days on this chart refer to Boulder weather over the last month. (8 pts). On the top chart above, circle the days that likely had a precipitation event (snow/rain). (7 pts). Estimate the energy content of the air, on the $1^{\text{st }}$ snow day last month $?$ Put a capital (S) on that point of the psychrometric chart. (8 pts). Estimate the energy content of the air, on the hottest day last month $?$ Put a capital $(\mathbf{H})$ on that point of the psychrometric chart. (7pts). If the temperature in New Orleans was $35\mathrm{C}$ and $70\%$ humidity, estimate the energy content of the air in that American city Put a capital (K) on that point of the psychrometric chart. (20 pts). For comfort, the temperature of classrooms are maintained no higher than $30\%\mathrm{RH}$ at $25\mathrm{C}$. A classroom contains approximately $1000\mathrm{kg}$ of air (a metric ton). The windows are open and the indoor air is in equilibrium with the outdoor air. Your boss wants to know what the energy bill is going to be after you close the windows and turn on the HVAC system; that is, how much energy (Joules) has to be moved: (1) into the room if class were held in Boulder on the first snow day last month; and (2), out of the room if the class were held in New Orleans?
