![Problem 2
A constant head permeability test was carried out on a cylindrical sample of sand 4 in. in diameter and 6
in. in height. 10 in3 of water was collected in 1.75 min, under a head of 12 in. Compute the hydraulic
conductivity in ft/year and the velocity of flow in ft/sec.
Problem 3.
A sand sample of 35 cm2 cross sectional area and 20 cm long was tested in a constant head
permeameter. Under a head of 60 cm, the discharge was 120 ml in 6 min. The dry weight of sand used
for the test was 1 120 g, and Gs = 2.68. Determine (a) the hydraulic conductivity in cm/sec, (b) the
discharge velocity, and (c) the seepage velocity.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F5b6d2e90-f469-4e70-84ea-72727c5d13c6%2F0b174135-e629-42d9-af13-d26cca54935e%2F1yzau8_processed.jpeg&w=3840&q=75)
