In a laboratory test of an aquifer material a fully saturated sample of volume 5 liters was taken and its initial weight of 105 N was recorded. When allowed to drain completely it recorded a weight of 97 N. The sample was then crushed dried and then weighed. A weight of 93 N was recorded at this stage. Calculate the specific yield and relative density of the solids.

Question

In a laboratory test of an aquifer material a fully saturated sample of volume 5 liters was taken and its initial weight of 105 N was recorded. When allowed to drain completely it recorded a weight of 97 N. The sample was then crushed dried and then weighed. A weight of 93 N was recorded at this stage. Calculate the specific yield and relative density of the solids. (Assume unit weight of water γγ=9.79 kN/m3)

Answers: Specific yield= 16.34%;

               Relative density of solids = 2.517
