(a) The maximum capillary rise of water to be expected in the glass tube is 30 mm.

(b) The maximum capillary rise of water to be expected between the  concentric glass tube is 30 mm.

Maximum capillary rise

The maximum capillary rise in the glass tube is calculated as follows;

[tex]h = \frac{2Tcos(\theta)}{r\rho g} \\\\[/tex]

where;

  • T is surface tension
  • r is radius = 0.5 x 1 mm
  • ρ is density
  • g is acceleration due to gravity

[tex]h = \frac{2 \times 0.0735 \times cos(0)}{0.5 \times 10^{-3} \times 1000 \times 9.8} \\\\h = 0.03 \ m\\\\h = 30 \ mm[/tex]

Maximum capillary rise between the glass tube

distance between glass tubes = 5 mm - 4 mm = 1 mm

radius of the glass = 0.5 mm

Maximum capillary rise =  30 mm
