= In the following capillary-rise experiment, calculate the height of capillary rise (h) if the contact angle = 0, water-air IFT = 70 dyne/cm, water density = 1 g/cc, air density = 0 g/cc (almost negligible), tube radius = 100 micron (or 0.01 cm), and gravitational acceleration = 980 cm/s2 h = cm A B h 21 tube o cos 62.70mbe = Apgh Toribe = (P.-P.) = = nube tube Based on the drawing at the interface, which phase can be viewed as internal phase near the interface, air or water? Based on the drawing at the interface, which phase has higher pressure near the interface, air or water? Calculate the magnitude of pressure discontinuity at the interface in (dyne/cm).
