The results of a constant-head permeability test for a fine sand sample having a diameter of 150 mm and a length of 300 mm are as follows (refer to Figure 7.5):
• Constant-head difference = 500 mm
• Water collected in 5 min = 350 cm3
• Void ratio of sand = 0.61
Determine:
a. Hydraulic conductivity, k (cm/sec)
b. Seepage velocity
