A lake is releasing pollutants into the air. The concentration of a pollutant in the lake is measured at 10 mg/L, while in the air, it’s 0.01 mg/L. Determine the conditions under which mass transfer is most effective. Consider flow rates and the role of temperature.
💡 Hint: Analyzing ambient conditions can provide insights into improving mass transfer.
Given a system where the individual resistances of liquid and gas phases are known as 100 and 10 respectively, calculate the overall mass transfer coefficient in the system. Consider the effect of increasing one of the resistances to 200.
💡 Hint: Focus on how these resistances interact in series.
