A falling-head permeameter contains a sample of length 10 centimeters and diameter 4 centimeters. The falling-head tube has an inside diameter of 1 centimeter. The nead falls from 5 to 2 centimeters over a period of 70 minutes. a. What is the hydraulic conductivity in cm/sec? . The water temperature was 21° C. At this temperature the density of water is 0.997 g/cm³ and the viscosity is 0.00988 g/sec-cm. What is the intrinsic permea- bility of the sample?
