Question

The weight of a pycnometer containing 400 g sand and water full to the top is 2150 g. The weight of pycnometer full of clean water is 1950 g. If specific gravity of the soil is 2.5, the water content is

Answer 1

Answer:

Wt. of Pycnometer + Wt. of Sand + Wt. of Water = 2150 g........(1).

Wt. of Pycnometer + Wt. of Water = 1950 g.......(2)

.Subtracting (1) from (2) we get

= 200 g.....Wt. of empty Pycnometer.

Therefore, W1 = 200 g,

W2 = W1(200 g) + Wt. of Sand(400 g) = 600 gW3 = 2150 g, W4 = 1950 g.

Replace this values in the above mentioned equation and you get the answer is 20%.
