displaced volume造句

• One common point of confusion regarding Archimedes'principle is the meaning of displaced volume.
• The upward buoyancy force on an object acts through the center of buoyancy, being the centroid of the displaced volume of fluid.
• Instead, in the case of submerged buoyant objects, the whole volume of fluid directly above the sample should be considered as the displaced volume.
• For each loading condition, the displaced water weight or buoyancy is calculated for that hull section based on the displaced volume of water within that hull section.
• For this reason, the mono-metal bullets similar to the Barnes TSX may have to be seated more deeply into the case displacing volume which could be filled with the propellant.
• :: : At the 7th grade level, " specific gravity " is essentially equivalent to " density . " There are a few nuances-if you want to be technical-but if you just want to measure specific gravity, you do so in the same way you measure mass-density : you weigh the object; and you measure its volume ( usually by measuring the displaced volume of water when you submerge the object ).
