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

Click For Summary
SUMMARY

The discussion centers on calculating the temperature at which the relative humidity in a pipeline containing an organic stream (primarily benzene and hydrocarbons) will reach 10%. The stream has a flow rate of 60 m3/h and contains 11 g/s of liquid water. Participants concluded that additional information, such as the specific heat and heat of vaporization of the mixture, is necessary for accurate calculations. Without knowing the amount of water vapor present, determining relative humidity is not feasible.

PREREQUISITES
  • Understanding of relative humidity and its calculation
  • Knowledge of specific heat and heat of vaporization concepts
  • Familiarity with organic stream properties, specifically benzene and hydrocarbons
  • Basic principles of thermodynamics in fluid systems
NEXT STEPS
  • Research the calculation methods for relative humidity in gas-liquid mixtures
  • Study the specific heat and heat of vaporization for benzene and hydrocarbons
  • Explore the principles of vapor-liquid equilibrium in chemical engineering
  • Learn about the impact of temperature on the solubility of water in organic solvents
USEFUL FOR

Chemical engineers, process engineers, and anyone involved in the design or analysis of fluid systems containing organic streams and water vapor interactions.

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.
