Section 4: Soil and Water Conservation Engineering

Soil Mechanics

Subtopic: Index properties of soils

Question Statement:

A moist soil sample weighing $115\text{ g}$ has an oven-dry weight of $100\text{ g}$. Calculate the gravimetric moisture content ($w$) of the soil on a dry weight basis in percentage.

Answer Key:

15

Step-by-Step Solution & Explanation

Weight of water $W_w = 115 - 100 = 15\text{ g}$. Moisture content dry basis: $w = \frac{W_w}{W_d} \times 100 = \frac{15}{100} \times 100 = 15.0\%$
