Why the Bore Diameter Matters
Water wets clean glass, so surface tension draws a column up the bore until the weight of the column balances the upward pull at the meniscus. The height follows Jurin’s law, h = 2T cos θ / (rρg): halve the radius and the water climbs twice as high. Plotting h against 1/r for several bores gives a straight line through the origin.
Getting a Clean Reading
Rinse the bore free of grease, then draw water above its rest level and let it fall back, so the meniscus settles on a wetted wall. Clamp the tube upright and measure the rise from the flat liquid surface to the bottom of the meniscus.
Related Surface Tension Apparatus
- Rising Table — holds the capillary in its clamp for the capillary rise experiment.
- Travelling Microscope — sights the meniscus through a cross-line eyepiece.
- Capillary Tubes — clear borosilicate capillaries of one stated bore.
More surface tension apparatus is in the Physics Lab range.
