1.     An open vessel containing 0.2 lb of liquid water placed in an empty room 5ft wide and 4ft deep and 7ft high, which initially contains dry air at 90F. All the water evaporates without changing the room temperature. Use the psychometric chart to estimate the relative humidity, wet bulb temperature, dew-point temperature, and specific enthalpy of the room air. Assume the mass of the dry air in the room stays constant at its initial value.
