A project engineer receives a laboratory report with tests performed on a certain soil sample on a particular location. The engineer suspects that one of the measurements is in error. Are the engineer's suspicions correct? If so, Which of these values is wrong, and what should be its correct value? Given: *Unit weight of the sample= 18.4 kN/cu.m *Unit weight of solids= 26.1 kN/cu.m *water content= 40% *void ratio= 1.12 *degree of saturation= 95% *

Question
Transcribed Image Text:A project engineer receives a laboratory
report with tests performed on a certain soil
sample on a particular location. The engineer
suspects that one of the measurements is in
error. Are the engineer's suspicions correct?
Which of these values is wrong, and what
If so,
so,
should be its correct value? Given: *Unit
weight of the sample= 18.4 kN/cu.m *Unit
weight of solids= 26.1 kN/cu.m *water
content= 40% *void ratio= 1.12 *degree of
saturation= 95% *
%3D
the unit weight of the sample in
O incorrect, thus the correct value is
17.2 kN/ cu.m
the unit weight of the solids is
O incorrect, thus the correct value is
25.2 kN/cu.m
the water content is incorrect, thus
the correct value is 42 %
the void ratio is incorrect, thus the
correct value is 0.112
the degree of saturation is incorrect,
thus the correct value is 0.95
all of the results were correct thuS
