FLUID MECHANICS Capillarity MY BOOK:- https://imojo.in/unitech108 It's the phenomenon of rise and fall of the liquid surface in small tube (diameter is less than 10mm) relative to adjacent level of liquid when tube is immersed vertically downward The rise of liquid is known capillary rise and the fall of liquid is known as capillary depression   $ads={1} Phenomenon Minicus=down Convexity=down Concavity=up Adhesion>cohession Wetting liquid θ<90° Minicus=up Convexity=up Concavity=down Adhesion<cohession Non Wetting liquid θ>90° $ads={2} Note For water (pure) and clean glass combination θ≈0° For clean glass and AgNO ₃ solution θ≈90° For clean glass and Mercury (hg) θ≈128°, θ≈125° to 140° capillary rise /depression is given by H=4Tcosθ/¶gd where,T=surface tension θ=contact angle d=diameter of tube ¶=density of liquid H=capillary rise/depression left sidebar contact form x
