Value, cylinder open top, cylinder body bottom connects the closing envelope equipped with counterweight.
This utility model one Novel densimeter, the density p of surveyed liquidLiquid=(V2-V0)/V1ρWater；In formula, V0According to
External volume data when graduation mark on cylinder and the empty densimeter of scale value record are put in water, V2For according on cylinder
External volume data when the densimeter loading liquid of external volume graduation mark and scale value record is put in water, V1For inside
Volume graduation mark and the volume loading liquid of scale value record.
This utility model one Novel densimeter, the density p of surveyed solidGu=(V3-V0)/(V4-V1)ρWater；In formula, V0For
External volume data when the densimeter loading liquid according to the graduation mark on cylinder and scale value record is put in water, V3For
Loading liquid and putting into the outer body when densimeter of solid is put in water according to the graduation mark on cylinder and scale value record
Volume data, i.e. (V3-V0) it is the densimeter volume that is immersed in the water change；V1For internal capacity graduation mark and the dress of scale value record
Enter the volume data of liquid.V4Loading liquid and putting into the volume number of solid for internal capacity graduation mark and scale value record
According to, i.e. (V4-V1) it is the volume of solid.
Compared with prior art, the beneficial effects of the utility model are:
This utility model simple in construction, with low cost, easy to operate, it is only necessary to can to draw corresponding by record and calculating
Density value, has also deepened student to liquid, the measurement of solid volume and the understanding of buoyancy formula and application while operation, and can
Measure the density of any liquid and solid, use very convenient, there is high promotional value.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of Novel densimeter of this utility model.
Wherein: cylinder 1, internal capacity graduation mark and scale value 2, external volume graduation mark and scale value 3；Equipped with counterweight
Close envelope 4.
Detailed description of the invention:
Seeing Fig. 1, a kind of Novel densimeter that this utility model relates to, described densimeter includes cylinder 1, described cylinder
1 is transparent cylinder (plastic cylinder, glass cylinder etc.), and the outer surface of cylinder 1 is uniformly labeled with internal capacity graduation mark and scale
Value 2, external volume graduation mark and scale value 3, cylinder 1 open top, connect bottom cylinder 1 and have the closing envelope 4 equipped with counterweight.
Operation principle of the present utility model is:
Cylinder 1 internal capacity is utilized to measure the volume V of object under test1, utilize cylinder 1 external volume to change (V2-V0) measure
The buoyancy that object under test is subject to, according to the gravity of object under test calculating determinand equal with the changing value of the buoyancy that cylinder 1 is subject to
The density of body.
Concrete operations are as follows:
When surveying the density of liquid, utilize cylinder 1 external volume graduation mark and scale value 3 to measure and record sky densimeter and put into
External volume data V time in water0；Utilize cylinder 1 external volume graduation mark and scale value 3 to measure and record and load the close of liquid
External volume data V when degree meter is put in water2, utilize cylinder 1 internal capacity graduation mark and scale value 2 measure and record loading
The volume V of liquid1。
According to gravity formulat:
G=ρLiquidV1g
Changing value according to buoyancy knowable to buoyancy formula:
FFloating change=ρWater(V2-V0)g
Gravity according to testing liquid is equal with the changing value of the buoyancy that cylinder 1 is subject to, i.e. G=FFloating change, it is known that:
ρLiquid=(V2-V0)/V1ρWater
V2、V0、V1Measure, ρWaterFor known constant；Therefore the density p of liquid can be calculated easilyLiquid。
When surveying the density of solid, the loading liquid measured according to the external volume graduation mark on cylinder 1 and scale value 3 and record
External volume data V when the densimeter of body is put in water0；Measure according to the volume markings line on cylinder 1 and scale value 3 and remember
Record loads liquid and puts into the external volume data V when densimeter of solid is put in water3, i.e. (V3-V0) it is that densimeter immerses water
The volume of middle change；Measure and record the volume V loading liquid according to cylinder 1 internal capacity graduation mark and scale value 21；
Measure according to cylinder 1 internal capacity graduation mark and scale value 2 and record and load liquid and put into the volume number of solid
According to V4, i.e. (V4-V1) it is the volume of solid.
According to gravity formulat:
GGu=ρGu(V4-V1)g
Changing value according to buoyancy knowable to buoyancy formula:
FFloating change=ρWater(V3-V0)g
Gravity according to solid to be measured is equal with the changing value of the buoyancy that cylinder 1 is subject to, i.e. GGu=FFloating change, it is known that:
ρGu=(V3-V0)/(V4-V1)ρWater
V3、V0、V4、V1Measure, ρWaterFor known constant；Therefore the density p of solid can be calculated easilyGu。
Additionally: it should be noted that above-mentioned detailed description of the invention is only a prioritization scheme of this patent, the skill of this area
Any change that art personnel are done according to above-mentioned design or improvement, all within the protection domain of this patent.
