Theory 31/Transport & flow/Capillary rise
Rise Is Tension Against Gravity
The claim
Capillary rise height is set by the ratio of surface tension to pore radius times gravity, so a fine pore lifts water higher but more slowly.
01Mechanism
Tension pulls water up while weight resists; the ratio sets the equilibrium height.
02Prediction
Height should track the ratio.
03Refutation
Height tracking pore size alone would remove gravity.
