Lecture 15: Capillary motion

Lecture 15: Capillary motion. Capillary motion is any flow governed by forces associated with surface tension. Examples : paper towels, sponges, wicking fabrics. Their pores act as small capillaries, absorbing a comparatively large amount of liquid. Water absorption by paper towel.
