An open container containing 0.205 lb of liquid water is placed in an empty room 5 ft wide, 4 ft deep, and 7 ft high, which initially contains dry air at 90 °F. All the water evaporates without modifying the ambient temperature. Use the psychometric diagram to estimate the final relative humidity, wet bulb temperature, wet volume, dew point temperature, and specific enthalpy of the room air. Assume that the molecular weight of dry air is 29 and, for simplicity, assume that the mass of dry air in the room remains constant and equal to its initial value.
