4.2 Fick’s law: exercise 1 (example)
4. First step into heat and mass transfer
When a droplet of ink is carefully inserted into a glass of water, the ink will start spreading throughout the water, resulting in some interesting mixing patterns which resemble modern paintings, such as the one shown in the picture above. Fick’s laws are experimentally derived laws which govern diffusion. When we speak of Fick’s Law, we normally mean Fick’s First Law: ϕm“=-D*dc/dx. In this exercise, your theoretical knowledge about the application of Fick’s First Law is tested.
