An open vessel 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 changing the room temperature. Use the psychrometric chart to estimate the final relative humidity, wet- bulb temperature, humid volume, dew-point temperature, and specific enthalpy of the room air. Take the molecular weight of dry air to be 29.0, and for simplicity, assume the mass of dry air in the room stays constant at its initial value.
