In an experimental setup, a chemical spills and begins to diffuse in water. If the concentration at the center is initially 10 kg/m³ and decreases to 2 kg/m³ over a given period, calculate the average mass flux during this time using Fick’s First Law.
💡 Hint: Remember to find the concentration difference and the distance infected by pollution.
A water tank evacuated through a pipe exhibits both heat loss and mass transfer. Define a situation where you would need to apply Fick’s Second Law to solve for the concentration as a function of time, and explain why it's necessary.
💡 Hint: Think of the relationship between outflow rate and concentration.
