At which temperature will the relative humidity in a pipeline be 10%?

TL;DR

In a pipeline is an organic stream (mainly benzene and hydrocarbons, 60 m3/h) which contains 11 g/s liquid water. At which temperature will the relative humidity in the pipeline be 10 %?

Is this possible to calculate? If not, which extra information would you need?

It isn't clear to me whether there's a process happening or not. Liquid water is liquid water, so it isn't affecting relative humidity, unless it is evaporating. Otherwise, the amount of water vapor isn't known...though it may always be 100% if the system is at equilibrium.

It seems like you would need to know the specific heat and heat of vaporization of the mixture.
