A long capillary tube of radius r = 1 mm open at both ends is filled with water and placed vertically. What will be the height (in cm) of the column of water left in the capillary in nearest integer? The thickness of the capillary walls is negligible. (surface tension of water is 72 dyne/cm and g = 1000 cm/sec 2 )
