The pressure and temperature of the mixture of air and water vapor at 1 bar and \(22^{\circ} \mathrm{C}\). The dew point temperature of the mixture is \(12^{\circ} \mathrm{C}\). Find partial pressure of water vapor in the mixture, relative humidity, specific humidity, enthalpy of mixture per \(\mathrm{kg}\) of dry air, and specific volume of mixture per kg of dry air.
