Homework #11 Distribution Date: 10-16-2023. Due Date: 10-19-2023. 1. Consider the falling-head permeability test and determine the hydraulic conductivity of the soil (cm/min) and the head difference at time t = 5 min: Length of the soil specimen = 500 mm Area of the soil specimen = 26 cm Area of the standpipe = 1.3 cm Head difference at time t = 0 = 760 mm Head difference at time t = 10 = 300 mm 2. Find the flow rate in m/s/m (at right angle to the cross section in figure 1) through the permeable soil layer: Direction of flow H=5 m H = 2.8 m h=3.1 m L = 60 m x = 5 k = 0.05 cm/s H h Impervious layer *107 Impervious layer
