Factors to consider

To calculate the maximum permissible exit gradient for soil with a factor of safety of 5, the following factors need to be considered:

- Specific gravity of the soil
- Porosity of the soil
- Factor of safety

Calculation

The maximum permissible exit gradient can be calculated using the following formula:

i(max) = (5-1) / (2.5 x 0.35)

where i(max) is the maximum permissible exit gradient.

Substituting the given values in the formula, we get:

i(max) = (5-1) / (2.5 x 0.35)
i(max) = 4 / 0.875
i(max) = 4.57

Therefore, the maximum permissible exit gradient is 0.195.

Answer

The correct answer is option C, which is 0.195.
