Determine the enthalpy of vaporization of water at \(150^{\circ} \mathrm{C}\), given that the saturation pressure is \(361.3 \mathrm{kPa}\) at \(140^{\circ} \mathrm{C}\) and \(617.8 \mathrm{kPa}\) at \(160^{\circ} \mathrm{C}\), and the specific volume at \(150^{\circ} \mathrm{C}\) is \(0.3917 \mathrm{~m}^{3} / \mathrm{kg}\).
