Question 1 of 5
1. Question2 points
Two soil specimens with identical geometric dimensions were subjected to falling head permeability tests in the laboratory under identical conditions. The fall of water head was measured after an identical time interval. The ratio of initial to final water heads for the test involving the first specimen was 1.25. If the coefficient of permeability of the second specimen is 5-times that of the first, the ratio of initial to final water heads in the test involving the second specimen is
Question 2 of 5
2. Question2 points
Two observation wells penetrating into a confined aquifer are located 1500m apart in the direction of flow. H eads of 50m and 25m are indicated at these two observation wells. If the coefficient of permeability for the aquifer is 30m/day and its porosity is 0.25, the time of travel of an inert tracer from one well to another is
Question 3 of 5
3. Question2 points
Consider the following statements:
1. Coarse sand is more than a million times permeable than a high plasticity clay.
2. The permeability depends on the nature of soil and not on properties of liquid flowing through soil.
3. If a sample of sand and a sample of clay have the same void ratio .both samples will exhibit the same permeability.
4. Permeability of soil decreases as the effective stress acting on the soil increases.
Which of these statements are correct?Correct
Question 4 of 5
4. Question2 points
A flow net constructed to determine the seepage through an earth dam which is homogenous but anisotropic, gave four flow channels
and sixteen equipotenital drops. The coefficient of permeability in the horizontal and vertical directions is 4.0 m/s and 1 m/s respectively. If the storage head was 20m, then the seepage per unit length of dam (in m3/s) would be
