For a psychrometric ratio of $1003 \mathrm{~J} \mathrm{~kg}^{-1} \mathrm{~K}^{-1}$, the latent heat of vaporization at the wet bulb temperature of $35^{\circ} \mathrm{C}$ is $2418.9 \mathrm{~kJ} \mathrm{~kg}^{-1}$. The saturation vapour pressure is $19.7 \mathrm{kPa}$ corresponding to the dry bulb temperature of $60^{\circ} \mathrm{C}$. If the relative humidity of air is $20 \%$, the saturation vapor pressure of the air at the wet bulb temperature in kPa will be______________
