Download Solution PDFIn a constant head permeameter with cross-sectional-area of 10 cm2 when the flow was taking place under a hydraulic gradient of 0.5, the amount of water, collected in 90 second was 900 cc. The permeability of the soil is :
Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFExplanation:
In constant head permeameter, flow is allowed to take place from the medium under constant head in order to find the permeability of the medium.
This method is suitable for coarse-grained soil in which substantial discharge could be obtained from the given time because the permeability of coarse-grained soil is very high.
We know
Q = kiA
\(k = \frac{Q}{{iA}} = \frac{{900/90}}{{0.5 × 10}}\)
k = 2.0 cm/sec
