Constant head permeability test

Permeability Test of Soil by Falling, Constant Head Permeameter.

SOLVED: A falling-head permeability test is performed on a soil whose permeability is estimated to be 2.8 x 10^-6 m/s. What diameter standpipe for head to drop from 31.2 cm to 19.4 cm in about 5 min? The cross section is 12 cm^2 and its length is 7.4 cm. (Taylor, 1948)?
