Technical data of product parameters
which is exactly the apparent weight of the object.
Note that the above analysis remains valid regardless of the position of the
object in the fluid. Thus the object can be completely surrounded by the fluid,
rest on the bottom of the container with no fluid under it, touch the walls of the PR9268201-000
container, or even float in the fluid with only a fraction of it submerged. In the
case of a floating object, however, the volume V in the above equations should
be taken to be the sub-volume of the object that is submerged.
A question that normally comes up during discussions of Archimedes’ principle is that when an object in the form of a rectangular block rests on the bottom of a container with no fluid under it, where does the upward buoyant force PR9268201-000
come from? In fact, in this case because of the fluid pressure on top of the block,
the net hydrostatic force on it would be downward, resulting in the apparent
weight of the block to be greater than its true weight. But this conclusion is in
complete contradiction with all observations since even in this case the apparent
weight of the block is less than its true weight by the weight of the fluid displaced.
To resolve this contradiction, one may argue that in reality when a submerged
object rests on the bottom of the container, there is almost always some fluid
between the surfaces that appear to be in contact unless the surfaces are specially
prepared and treated to prevent fluid seepage. This is because for ordinary flat PR9268201-000
surfaces, the actual area of contact is always much smaller than the apparent
contact area [16] [17]. In fact the real contact area can be less than the apparent An object denser than a fluid rests on the bottom of a container filled with
the fluid. A weight scale is also located at the bottom of the container. The dashed region
shows a volume of the fluid equal to the volume of the object; (b) The object has been
moved to the top of the scale, displacing an equal volume of the fluid from that region.
