Refer to the constant-head permeability test arrangement in a two-layered soil as shown in Figure 8.2. During the test, it was seen that when a constant head of h1= 200 mm was maintained, the magnitude of h2 was 80 mm. If k1 is 0.004 cm/sec, determine the value of k2 given H1 = 100 mm and H2 = 150 mm.
