A falling head permeability test was carried out on a 15 cm long sample of silty clay. The diameter of the sample and the stand pipe were 10.2 cm and 0.82 cm respectively. The water level in the stand pipe was observed to fall from 60 cm to 42 cm in 14 minutes. What will be the height of water level (in cm) in the stand pipe after 22 minutes?
