A well-mixed open pond contains wastewater that is contaminated with a dilute concentration of dissolved methylene chloride.
Question:
a. At what position across the pond is the air flow no longer laminar? Would it be reasonable to assume that the mean film mass-transfer coefficient for methylene chloride in air is dominated by turbulent flow mass transfer?
b. As part of an engineering analysis to predict the emissions rate of methylene chloride (species A) from the pond, determine the average gas film mass-transfer coefficient associated with the mass-transfer methylene chloride from the liquid surface to the bulk air stream.
c. Compare the Schmidt number for methylene chloride in the gas phase vs. the liquid phase, and explain why the values are different.
