කේශාකර්ෂණය

Capillary water flow up a 225 mm-high porous brick after it was placed in a shallow tray of water. The time elapsed after first contact with water is indicated. From the weight increase, the estimated porosity is 25%.

Capillary action of water (polar) compared to mercury (non-polar), in each case with respect to a polar surface such as glass (≡Si–OH)

කේශාකර්ෂණය (ඉංග්‍රීසි:  Capillary action, capillarity, capillary motion, capillary rise, capillary effect, හෝ wicking) යනු ගුරුත්වාකර්ෂණය වැනි බාහිර බලවේගවල සහාය නොමැතිව පටු අවකාශවල ද්‍රව ගලා යාම ආශ්‍රිත ක්‍රියාවලියකි.
