the unit weight is in KN/m3 for above and below the groundwater
the unit weight is in KN/m3 for above and below the groundwater
Homework Answers
The soil or sand will have unit weight in (KN/(m^3)) for
above and below the ground water which is in
metric units.
In imperial units, the unit weight is (lbs/(ft^3)).
Because, the weight of a soil or sand is
expressed in terms of force per unit volume.
