A falling-head permeability test on a specimen of fine sand 12.5 cm2 in area and 10 cm

Question:

A falling-head permeability test on a specimen of fine sand 12.5 cm2 in area and 10 cm long gave a k of 6.2 x 10-4 cm/s. The dry mass of the sand specimen was 195 g and ρs was 2.71 Mg/m3. The test temperature was 23°C. Compute the coefficient of permeability of the sand for a void ratio of 0.67 and the standard temperature of 20°C. (After A. Casagrande)?
