What calculation A soil sample has a degree of saturation of 30.4 percent and void ratio of 0.85How much water must be added per cubic foot of soil to increase degree of saturation to 100 percent?

Answer 1

Void ratio

is 0.85. Hence, the ratio of

pore space

and mineral is 85/100.

So for 1

cub

ft of soil the volume of pore space is 0.85 cu ft.

Now out of this 0.85 cu ft of pore space, 30.4% is already filled by water.

So there should be a further 69.6% of water required to arrive at 100% saturation.

69.6% of 0.85 cub ft = 59.16 cub ft

The ans is 59.16 cub ft of water must be added to make the soil 100% saturated
