A soil borrow material in its natural state in the ground has a unit weight of 123 pcf. When a sample is dried in oven in laboratory. Its dry unit weight is 103 pcf. What is the water content of this borrow material?

The water content of this borrow material is 0.194

Explanation:

Given that,

Weight of material = 123 pcf

Weight of dry sample = 103 pcf

We need to calculate the water content of this borrow material

Using formula of water content

Where, w = weight of water

= dry unit weight

= unit weight

Put the value into the formula

Hence, The water content of this borrow material is 0.194
