Question
A volume of moist sand weighs . Its dry weight is and specific gravity of solids, is 2.67. Assuming density of water as , the void ratio is _______________.
Correct answer
0.7 to 0.72
Solution
Given:
Total volume,
Total weight,
Dry weight,
Specific gravity,
Density of water, Step 1: Calculate the dry density ():Step 2: Use the relationship between dry density, specific gravity, and void ratio ():The void ratio is approximately 0.71.
