Given that the viscosity of blood is 0.017 poise and the density of blood is 1.02 g/cm^3.

A long capillary tube of radius 1 cm open at both ends is filled with water and placed vertically. What will be the height of water column left in the capillary ? (Surface tension of water = 72 dyne/cm and density of water = 1 g/cm^3.)
