Show hintHide hint
Think about the units involved.
Question 2.
Define mass transfer coefficient.
Show hintHide hint
Remember its relation to phase changes.
3Question 3.
What does the mass transfer coefficient indicate?
- Rate of evaporation
- Rate of flow between phases
- Concentration at equilibrium
Show hintHide hint
Think about the role of the coefficient in transition between states.
4Question 4.
True or False: Evaporation flux is solely determined by temperature.
- True
- False
Show hintHide hint
Consider all factors affecting flux.
Question 5.
A lake with a chemical concentration of 50 mg/L is assumed to have a mass transfer coefficient of 0.1 m/s. Calculate the evaporation flux if the area exposed to air is 1000 m².
