Question
Oedometer A is manual with porous stones at top and bottom and has a sample 16 mm thick. Oedometer B is hydraulic with drainage at the bottom only and has a sample 8 mm thick. The maximum drainage path, H, for A and B, respectively, will be:Group of answer choices8 mm and 8 mm16 mm and 4 mm16 mm and 8 mm8 mm and 4 mm
Solution
The maximum drainage path, H, for Oedometer A and B will be 8 mm and 4 mm respectively.
Here's why:
For Oedometer A, which is manual with porous stones at top and bottom, the drainage can occur from both the top and the bottom. Therefore, the maximum drainage path is half the thickness of the sample, which is 16 mm / 2 = 8 mm.
For Oedometer B, which is hydraulic with drainage at the bottom only, the drainage can only occur from the bottom. Therefore, the maximum drainage path is the full thickness of the sample, which is 8 mm. However, because the drainage is only from one side, we consider half the thickness as the maximum drainage path, which is 8 mm / 2 = 4 mm.
