    3. c)

      Soil sample of 80 mm diameter with length of 300 mm used for constant head test. The loss of head 1100 mm and the rate of flow was 2700 mm 3 /sec. Find the coefficient of permeability in mm/sec. If falling head test was performed on the same sample at the same void ratio, find the time taken for head to fall from 900 mm to 550 mm. The diameter of stand pipe is 25 mm in falling head test. 
