How much volume is below water?nwmyname said:The density of the object is 525 kgm-3 and the density of the water is 1000 kgm-3 so it must be sink 52.5% into the water?
A much more useful application of Archimedes' Principle would be to find out the draft that the block must float at such that the weight of water displaced by the block is equal to the weight of the block itself. The draft of the block is that distance the bottom sinks below the surface of the water, and given the shape of the block, a trivial calculation.nwmyname said:Homework Statement
A block of wood measures 2.2m by 2.5m with depth 3.6m with weight 102KN. When placed in water, how far will it sink?
g = 9.81 ms-2
density of water = 1000kg m-3
Homework Equations
The Attempt at a Solution
Volume = 2.2(2.5)(3.6) = 19.8m3
Mass = 102000 / 9.81 = 10398 kg (nearest whole)
Density = 10398 / 19.8 = 525 kg m3
It sinks 52.5% of the water.
How to continue finding how far it will sink?
It sinks 52.5% of what into the water? 52.5% of the block?nwmyname said:The density of the object is 525 kgm-3 and the density of the water is 1000 kgm-3 so it must be sink 52.5% into the water?
