Challenge Problems
Push your limits with challenges.
Question 1
A rod with a length of 2 meters has a concentration of 10 kg/m³ on one end and 5 kg/m³ on the other. Calculate the diffusive mass flux assuming D = 0.1 m²/s.
💡 Hint: You're looking for the change in concentration over the length of the rod.
Question 2
Solve for the concentration profile of a transient diffusion scenario where initial concentration at x=0 is 100 kg/m³ and decays with time using the diffusion equation.
💡 Hint: Consider how the initial conditions affect the concentration over time.
