Final answer:
The student is tasked with calculating the stripping factor and expected effluent concentration of benzene in an air stripping device using given flow rates and initial concentrations.
Step-by-step explanation:
The student is interested in calculating the stripping factor for an air stripping device and the expected effluent concentration of benzene.
Given the water flow rate of 10 l/min and the air flow rate of 219.3 l/min, with the initial concentration of benzene in water being 1 mol/l and in the air 0 ppm, the stripping factor can be found using the ratio of air to water flow at equilibrium concentrations according to Henry's law.
Without specific details on benzene's volatility and the system's equilibrium data, a numerical answer cannot be provided for the stripping factor or the expected effluent concentration in this answer format.
