Question
Figure below shows layers of soil in a tube that is 100mm x 100mm in
cross section. Water is supplied at a constant head difference of 400 mm across the
sample. The hydraulic conductivities of the soils in the direction of flow through them are
as follows.
Soil | k (cm/sec) | Porosity, n (%) |
A | 1x10-2 | 25 |
B | 3x10-3 | 32 |
C | 4.9x10-4 | 22 |
a. Calculate the equivalent k in cm/sec.
b. Calculate the rate of water supply in cm^3/hr
c. Calculate the seepage velocity through soil C in m/sec.
