In the Physical Experiment of middle school or university, the experiment of checking Bernoulli equation is arranged.Experiment purpose is to observe fluid when stable-state flow, and the transforming relationship when flowing through different cross section between energy, instruction of papil can utilize Bernoulli equation to solve relevant issues.Lead in the experiment and will adopt the Bernoulli equation experimental provision.The most volumes of existing Bernoulli equation experimental provision are larger, and structure is complicated, and each section of barretter sectional area is non-adjustable.
Summary of the invention
For addressing the above problem.The utility model provides a kind of Bernoulli equation experimental provision, and this Bernoulli equation experimental provision small volume is simple in structure, is provided with the long-pending pipeline section of place's variable-area at barretter, and capable of dynamic is measured the relation of flow rate of liquid and pressure.
The technical scheme that the utility model technical solution problem adopts is: invent a kind of Bernoulli equation experimental provision, be characterized in: the Bernoulli equation experimental provision has a weighing apparatus setting-out case, connect a barretter in weighing apparatus setting-out case bottom, connect a U-shaped pipe on the barretter, a flow area adjusting gear is installed on the barretter, barretter connects a recovery tank, connect a return pipe at weighing apparatus setting-out upper box part, the other end of return pipe passes into recovery tank, and a water pump is connected between weighing apparatus setting-out case and the recovery tank by pipeline.
The beneficial effects of the utility model are, this Bernoulli equation experimental provision small volume is simple in structure, are provided with the long-pending pipeline section of place's variable-area at barretter, and capable of dynamic is measured the relation between flow rate of liquid and the pressure.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Accompanying drawing is the structural drawing of present embodiment.1 weighing apparatus setting-out case among the figure, 2 return pipes, 3 water injection pipes, 4 filling openings, 5 mouthfuls of plugs, 6U shape pipe, 7 water pumps, 8 drinking-water pipes, 9 recovery tanks, 10 scales, 11 adjusting nuts, 12 valve bodies, 13 valve pockets, 14 barretters, 15 bases.
Embodiment
As shown in drawings, weighing apparatus setting-out case 1 bottom connects a barretter 14, connect U-shaped pipe 6 on the barretter 14, be provided with filling opening 4 on the top of U-shaped pipe 6, in filling opening 4, be equipped with a mouthful plug 5, a flow area adjusting gear is installed on the barretter 14, the flow area adjusting gear is by scale 10, adjusting nut 11, valve body 12 and valve pocket 13 consist of, the water delivering orifice of barretter 14 is connected on the recovery tank 9, top at weighing apparatus setting-out case 1 connects a return pipe 2, the other end of return pipe 2 passes into recovery tank 9, drinking-water pipe 8 is installed in bottom at recovery tank 9, and the other end of drinking-water pipe 8 connects the water inlet of water pump 7, and the water delivering orifice of water pump 7 connects water injection pipe 3, the other end of water injection pipe 3 passes into weighing apparatus setting-out case 1, and weighing apparatus setting-out case 1 and recovery tank 9 are installed on the base 15.
When doing experiment, at first taking off a mouthful plug 5, to an amount of liquid of U-shaped pipe 6 interior injections, also can be water, then smears a little seal greases at mouth plug 5, can be vaseline, and mouth plug 5 is inserted filling opening 4 with its sealing.Again to recovery tank 9 interior water fillings, after filling with water, starting water pump 7 draws water in weighing apparatus setting-out case 1, after water in the weighing apparatus setting-out case 1 is filled it up with, water can be from return pipe 2 to recovery tank 9 flows into, behind the stability of flow of water in the return pipe, water level in the weighing apparatus setting-out case 1 is also just stable, water in the weighing apparatus setting-out case 1 flows into recovery tank 9 by barretter 14, and this moment, the flow velocity of barretter 14 interior water was basicly stable, adjusts adjusting nut 11 with reference to scale 10 and changes the position of valve body 12 in valve pocket 13, the partial cross section that changes barretter 14 is long-pending, observe the poor Changing Pattern of liquid level in the U-shaped pipe 6, the phenomenon that occurs in the experiment is carried out observation analysis, deepen the understanding to Bernoulli equation.
