Hey guys, I am a little confused with the concept of Capillary actions with specific regards to paper towels. I understand the mechanics behind a single capillary tube and the height that water reaches in relation to surface tension. However, my professor claims that paper towels absorb as if a lot of capillary tubes are bunched up together, and function based on capillary action. I sort of get this, but I can't seem to grasp how the equation for a single capillary tube would transfer over to a paper towel. I.E how to find the height of water that a paper towel will absorb based on the capillary equation. Would someone mind helping me see this?
