A capillary permeability test was conducted in two stages under a head of 60 cm and 180 cm. In the first stage, the wetted surface moved 1.5 cm to 7 cm in 7 minutes. In the second stage, it advanced from 7 cm to 18.5 cm in 24 minutes. The degree of saturation at the end of the test was 85% and the porosity was 35%. Determine the capillary head and coefficient of permeability.
