railway RRB JE (CBT I + CBT II) Mock Test 2024 Fluid Mechanics Properties of Fluids Capillary Action
If diameter of the capillary tube (d), surface tension force for unit length (σ) and weight density (w), then the capillary rise of water in the glass tube (h) will be given by:
(Consider angle of contact between water and the glass tube is zero)
1
h = 2σ/wd
2
h = 3σ/wd
3
h = 4σ/wd
4
h = 6σ/wd
