Challenge Problems
Push your limits with challenges.
Question 1
Calculate the expected flux of a substance at a boundary layer given a concentration difference of 0.5 mol/m^3, and a mass transfer coefficient of 1.2 m/s.
💡 Hint: Remember the relationship between flux, concentration difference, and mass transfer coefficient.
Question 2
Discuss how increasing the turbulence of a flow would affect mass transfer rates at the boundary layer. Provide a qualitative reasoning.
💡 Hint: Think about chaotic fluid movement versus smooth layering.
