Question

F the depth of moist sand in a cylinder is 15 cm and the depth of the sand when fully inundated with water is 12 cm, the bulking of the moist sand, is 1 point



a. 10%



b. 12%



c. 15%



d. 20%



e. 25%.

Answer 1

Answer: Option E

Explanation:

Formula = {(h-h1)/h1)}*100, h = 15, h1 = 12.

= {(15-12)/12}*100,

= (3/12)*100,

= 0.25*100,

= 25%.

Answer 2

Concept

Bulking of sand refers to the increase in sand volume brought on by an increase in moisture content. The sand particles are surrounded by a thin layer of water, which causes the particles to move apart and increase the volume. Sand's bulk rises as its moisture content rises.

Given

• The depth of cylinder given is 15cm
• The depth of the sand given is 12 cm
• The bulking of moist sand given is 1 point

Find

We need to find the % of bulking moist sand

Solution

Given :

H = 15cm (Depth of Cylinder)

h = 12cm (Depth of Sand)

To calculate the bulking point of moist sand

H-h / h *100

= 15 - 12 / 12*100

= 3/12*100

=0.25*100

= 25%

Hence the bulking of moist sand is 25%
