cm/s.
What amount of water in (gr) do we have to add to a soil sample to increase its volume to 25 cm3? We know the following information about this soil: - Soil’s specific gravity is 2.5. - Void ratio (e) is 0.5. - Moisture content is 20%. - The water density is 1 gr/cm3. Hint 1: First calculate the saturation value. Hint 2: When soil is fully saturated, if we add V1 amount of water (m3), the volume of soil will increase directly by V1 (m3). Hint 3: Use the following equation to find the answer: Question 17Answer a. 50 b. We do NOT have enough information c. 12.5
