Question 2.
What does the mass transfer coefficient measure?
Show hintHide hint
Consider how it influences the rate of flux.
3Question 3.
What is the driving force of mass transfer?

Show hintHide hint
Consider factors that affect mass transfer.
Question 5.
A river has a concentration of a pollutant at its surface as 50 mg/L. If the concentration decreases to 5 mg/L at 10 cm from the surface, calculate the concentration gradient.
Show hintHide hint
Use the formula for concentration gradient.
Question 6.
Describe how increasing fluid velocity affects mass transfer in both laminar and turbulent flow scenarios. Provide an example scenario.
Show hintHide hint
Consider both flow conditions and how they differ.
