Challenge Problems
Push your limits with challenges.
Question 1
In a chemical reactor, the mass transfer coefficient for a reactant is measured at 5.0 m/s. Given a concentration of 20 mol/m^3 at one end and 0 mol/m^3 at another, calculate the expected mass transfer rate.
💡 Hint: Don't forget the relationship between mass transfer rate, coefficient, and concentration difference.
Question 2
Describe what would happen to mass transfer efficiency if turbulence in the flow decreased significantly. Provide reasoning.
💡 Hint: Consider how fluid movement impacts concentration gradients.
