Q

Why is the specific volume useful?

A

It provides a way of representing how much bigger the overall body is compared to the size of the solids.

16
Q

What is the water content?

A

The mass of water within the soil element relative to the mass of the solids.

17
Q

What is air mass in soil taken as?

A

Zero

18
Q

What is the saturation ratio?

A

How much water there is in the voids relative to the maximum possible volume which could be stored in the voids

19
Q

What is the equation of the saturation ratio?

A

Volume of water / volume of voids = wGs / e

20
Q

What is the symbol for the saturation ratio?

A

Sr

21
Q

What is the symbol for the air volume ratio?

A

A

22
Q

What is the definition of the Air Volume ratio?

A

The ratio of the volume of air to the total volume of the element

23
Q

What is the equation of the air volume ratio?

A

Vair / Vtotal = e(1-Sr) / 1+e

24
Q

What is the equation of the bulk density of soil?

A

p = ( (Gs + Sre) / 1+e ) X the density of water

25
Q

What is the equation of the dry density of soil?

A

p = ((Gs + 0e) / 1+e ) X density of water = (Gs/1+e) X density of water
