The capillary rise in the glass tube is not to exceed 0.2 mm of water. Determine its minimum size, given that surface tension for water in contact with air = 0.0725 N/m.
Q. The capillary rise in the glass tube is not to exceed 0.2 mm of water. Determine its minimum size, given that surface tension for water in contact with air = 0.0725 N/m. SOLUTION: Capillary rise, h = 0.2mm = 0.2 * 10³ m Surface tension σ = 0.0725N / m Let dia. of tube … Read more
