Question

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?

Answer 1

Answer:

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

$\gamma_{d}=\dfrac{\gamma}{1+W_{w}}$

$W_{w}=\dfrac{\gamma-\gamma_{d}}{\gamma_{d}}$

Where, w = weight of water

$\gamma_{d}$ = dry unit weight

$\gamma$ = unit weight

Put the value into the formula

$W_{w}=\dfrac{123-103}{103}$

$W_{w}=0.194$

Hence, The water content of this borrow material is 0.194
