allowed to flow through
stalagmometer 50 drops were
obtained. When same volume of
unknown liquid is allowed to
flow 35 drops were obtained. If
density of unknown liquid is
1.287 g/ml. What will be the
Surface tension of unknown
liquid? ( density of water = 0.996
g/ml, surface tension of water =
72 x 10-3 N/m)
