1. (50 pts) Moist air at standard conditions is at a dry bulb temperature of \( 93^{\circ} \mathrm{F} \) and a wet bulb temperature of \( 62^{\circ} \mathrm{F} \). Use the psychrometric chart to find: b. The relative humidity c. The dew point temperature d. The humidity ratio c. The specific volume f. The enthalpy 2.(50 pts) Moist air at standard conditions is at a dry bulb temperature of \( 50^{\circ} \mathrm{F} \) and a relative humidity of \( 70 \% \). It is sensibly heated (constant moisture) to \( 72^{\circ} \mathrm{F} \). Use the psychrometric chart to determine the heating energy needed per pound of dry air.
