: The following data were recorded in a constant head permeability test. Internal diameter of permeameter = 7.5 cm Head lost over a sample length of 18 cm = 24.7 cm Quantity of water collected in 60 s = 626 ml Porosity of the soil sample was 44% Calculate the coefficient of permeability of the soil. Also determine the discharge velocity and the seepage velocity during the test. If the test was carried out at a temperature of 25°C, estimate the permeability of the soil for a porosity of 39% and at 20°C.
