Abstract
The invention relates to a tool commonly used for measuring liquid in a laboratory, in particular to a measuring cylinder capable of measuring the weight of kerosene. According to the measuring cylinder capable of directly measuring the weight of liquid, the liquid volume measuring function of a traditional measuring cylinder is achieved and meanwhile the weight of the liquid can be directly measured. According to the technical scheme, a scale indicating the weight of the liquid and the weight numerical values of the liquid are engraved on the outer wall of the traditional measuring cylinder according to the actual requirements, wherein a kerosene scale indicating the weight of the kerosene and weight numerical values of the kerosene are taken for example in the measuring cylinder capable of measuring the weight, the scale and the weight numerical values of the kerosene are determined according to an original volume scale value and the density of the liquid with certain mass to be measured, the mass of the liquid to be measured is obtained through calculation according to a formula that the density=m/v, and then the weight of the liquid to be measured is calculated according to a formula that G=mg, wherein g=9.8N/kg. When the weight of a certain liquid is measured, a number can be directly read according to the weight scale on the measuring cylinder. The measuring cylinder capable of measuring the weight has the advantages that when the weight of the liquid is measured through the measuring cylinder, the weight of the liquid in the measuring cylinder can be directly read according to the weight scale, the cost of the product is extremely low, and operation is convenient.
Description
Affiliated technical field
The present invention relates to the instrument of a kind of conventional measurement liquid in laboratory, especially a kind of graduated cylinder with measurement kerosene weight function.
Background technology
Graduated cylinder is the special measurement instrument of measuring liquid volume.When laboratory measurement liquid weight, conventional method is, first with graduated cylinder, measures the volume of testing liquid, then by tabling look-up, obtains the density of this testing liquid, then by density formula
=m/v calculates the quality of this testing liquid, then according to G=mg, gets the weight that g=9.8N/kg calculates testing liquid.Method records weight thus needs first measurement volumes recycling formula to calculate, and feels very inconvenient.
Summary of the invention
In order to overcome the deficiency that adopts said method, the invention provides a kind of graduated cylinder that can measure liquid weight, its existing traditional graduated cylinder can be measured the function of liquid volume, can directly measure the weight of liquid again simultaneously.
The technical solution adopted for the present invention to solve the technical problems is; On traditional graduated cylinder outer wall according to actual needs, engrave the scale mark of at least one liquid weight and weight numerical value thereof (the present invention take weight scale line and the weight numerical value thereof of measuring kerosene are provided be example), determining of its scale mark and weight numerical value, the density by original volume scale value and weight liquid to be measured, first by
=m/v formula calculates the quality of testing liquid, then by G=mg, gets the weight that g=9.8N/kg calculates testing liquid, like this, when measuring certain liquid weight, can be from the direct reading of weight scale line.
The invention has the beneficial effects as follows, while measuring liquid weight by graduated cylinder, can directly by weight scale line, be read the weight of liquid in graduated cylinder.Cost of products is extremely low, easy to operate.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is the graduated cylinder structural representation of traditional measurement liquid volume.
Fig. 2 is embodiment of the present invention structural representation.
1. graduated cylinder outer walls in figure, 2. volume markings line, 3. volume markings value, 4. volume range maximal value, 5. volume unit, 6. weight scale line, 7. weight scale value, 8. weight range maximal value, 9. unit of weight.
Embodiment
The present embodiment is to be on 0 ~ 100ml traditional measurement liquid volume graduated cylinder, to increase the function of measuring kerosene weight at range.By scheming, first by maximum range value (4) 100ml of volume be 0.8kg/m by the density that density meter checks in kerosene
3, then according to density formula
the maximal value that=m/v calculates this graduated cylinder measurement kerosene liquid quality is 80g, again by G=mg, getting the maximum range value that g=9.8N/kg calculates kerosene liquid weight to be measured is 0.784N, gets two position effective digitals, and to survey the maximum range value of kerosene be 0.78N to this graduated cylinder.At graduated cylinder outer wall (1) volume range maximal value (4) equal-height position, carve weight range maximal value (8) 78N thus.At the zero graduation line equal-height position of volume markings line (2), carve the zero graduation line of weight, and then carve equably scale mark (6) by carrying out 78 deciles between weight maximum range value (8) scale mark and zero graduation line, and the minimum division value that known this graduated cylinder is measured liquid weight is 0.01N.Place, top at weight scale line (6) carves unit of weight (9) N.All scale marks of this graduated cylinder, numeral, unit all can disposablely complete when production.
Claims (2)
1. the graduated cylinder that can directly measure liquid kerosene weight, comprise scale mark (2), numeral (3), the unit (5) of measuring liquid volume and the scale mark (6) of measuring kerosene weight, numeral (7), unit (9), it is characterized in that: on the graduated cylinder of measurement volumes, increase at least one scale mark (6) of measuring liquid weight, numeral (7), unit (9).
2. according to the graduated cylinder of the measurement liquid kerosene weight described in claim 1, it is characterized in that: the scale mark (6), numeral (7), unit (9) of measuring liquid weight with the scale mark (2) of the former measurement liquid volume of graduated cylinder, digital (3), unit (4) with the disposable generation in the production of graduated cylinder of identical method for making.
