====== Capillary Tubes ====== {{tag> fluid_mechanics surface_tension located}} {{IMG_2220.jpg?400|}} // // ===== Description ===== A series of glass tubes with different internal diameters, all connected by a bigger glass tube at the bottom. Comes with a plastic stand. ===== Purpose ===== To show capillary action in narrow tubes and to show that the rise is greatest for the smallest diameter tube for water. ===== Apparatus ===== * Capillary apparatus * Dyed water ===== Setup ===== Fill apparatus as shown with coloured water, and set up a close-up camera (if necessary) to closely compare the height of each column of water. Pascals principle dictates that the water should be level in each tube, but the capillary effect causes a visible deviation from this. ===== Notes ===== // Demo room information // | **Location** | C4 | | **Maker** | Unknown | | **Current State** | Working |
