(ii)A capillary permeability test was conducted in two
stages under a head of 80 cm and 160 cm, respectively,
at the entry end. In the first stage, the wetted surface
moved from 2 to 8 cm in 8 minutes. In second stage,
it advanced from 8 cm to 20 cm in 25 minutes. The
degree of saturation at the end of the test was 80%
and porosity was 40%. Determine the capillary head
and the coefficient of permeability.
