10 L/min outside air (1.1 atm, 32°C, 58% relative humidity) is bubbled through a column fed by 200 mL/min pure n-pentane at 15°C to produce a process stream at 15°C consisting of air, water, and pentane. No water dissolves in the pentane, and the Henry's Law constant for air in pentane is 5.3 x 103 mol fraction/atm.

Question
**Problem Statement:** 10 L/min outside air (1.1 atm, 32°C, 58% relative humidity) is bubbled through a column fed by 200 mL/min pure n-pentane at 15°C to produce a process stream at 15°C consisting of air, water, and pentane. No water dissolves in the pentane, and the Henry’s Law constant for air in pentane is 5.3 x 10⁻³ mol fraction/atm. Determine the compositions (mole fractions of all components present) of all four streams, and the total molar flow rates of all streams. **Diagram Description:** - The process system diagram features an input of n-pentane at 200 mL/min entering a column. - There is an input stream of outside air at 32°C, 1.1 atm, 58% relative humidity with a flow rate of 10 L/min. - Four streams are labeled in the diagram: 1. **n₁ mol/min**: Input of n-pentane, right before entering the column. 2. **n₂ mol/min**: Represents the n-pentane entering the column. 3. **n₃ mol/min**: Represents the output stream of the column at 15°C, 1.0 atm, containing air, water, and pentane. 4. **n₄ mol/min**: Represents an additional interaction or output related to the system at 15°C. The process involves calculating the mole fractions and total molar flow rates based on provided variables and chemical laws, such as Henry's Law, which describes the solubility of gases in liquids.
