Partially saturated air at 1 bar and 50 °C is contacted with water in an adiabatic saturator. The air is cooled and humidified to saturation, and exits at 25 °C with an absolute humidity of 0.02 kg water per kg dry air. Use latent heat of vaporization of water as 2450 \(kJ.kg^{-1}\), and average specific heat capacity for dry air and water, respectively as 1.01 \(kJ.kg^{-1}K^{-1}\) and 4.18 \(kJ.kg^{-1}K^{-1}\). If the absolute humidity of air entering the adiabatic saturator is H x\(10^{-3}\) water per kg dry air, the value of H is_______ (rounded off to two decimal places).
