Abstract
The utility model relates to an experimental device, and, more specifically, relates to a safe and healthy experimental device for verifying the relation of fluid pressure intensity with flow velocity. The device comprises a table tennis ball 1, a gas-guide tube 2, a ball needle 3, a basketball 4, and a step glass tube 5. The device is characterized in that the gas-guide tube 2 is connected with the basketball 4 through the ball needle 3; and the other end of the gas-guide tube 2 is connected with the bigger end of the step glass tube 5. According to the other mode of execution, the gas-guide tube 2 is connected with the basketball 4 through the ball needle 3, the other end of the gas-guide tube 2 is connected with the bigger end of the step glass tube 5, and the smaller end of the step glass tube 5 is connected with an inserting hopper 6. According to the utility model, the basketball 4 is used for replacing mouth blowing, thereby visually reflecting the relation of the fluid pressure intensity with the flow velocity, and motivating students for learning physics. Meanwhile, the device is safe and healthy, and prevents pathophoresis.
Description
Technical field
The utility model relates to a kind of experimental provision, more specifically to a kind of safety and sanitation checking " fluid pressure and flow velocity relation " and experimental provision.
Background technology
" table tennis can fall down? " this experiment is an experiment of behaving excellently most in grade eight physics preamble, has to excite the interest of Students ' Learning physics, even have an effect that leads student to come into science gate.Design on teaching material is to blow with mouth, but such design has following two weak points at least: 1, unhygienic, and 2, unstable, the duration is short.
Utility model content
The purpose of this utility model is: the experimental provision of a kind of safety and sanitation checkings " fluid pressure and flow velocity relation " is provided, utilizes basketball as source of the gas, solved dexterously above-mentioned deficiency.
The utility model comprises table tennis, wireway, ball pin, basketball, step glass tube, and its feature is: wireway is connected with basketball by ball pin, and the other end of wireway is connected with the stub end of step glass tube.
The utility model has the advantage of: utilize basketball as source of the gas, health, experiment are stablized, and the duration is long.
" table tennis can hover over glass tube top and can follow glass tube all around and move ", this experiment also can utilize basketball to demonstrate as source of the gas, and experiment effect is ideal.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is the 1st kind of embodiment structural representation of experimental provision of a kind of safety and sanitation checkings of the utility model " fluid pressure and flow velocity relation ".
Fig. 2 is the structural representation of the 2nd kind of embodiment of experimental provision of a kind of safety and sanitation checkings of the utility model " fluid pressure and flow velocity relation ".
In Fig. 1: wireway 2 is connected with basketball 4 by ball pin 3, the other end of wireway 2 is connected with step glass tube 5 stub ends, utilizes basketball 4 as source of the gas, its effect: health, duration are long.Experimental result: table tennis can hover over glass tube 5 tops and can follow glass tube 5 all arounds and move, experiment is stable, and the duration is long.
In Fig. 2: wireway 2 is connected with basketball 4 by ball pin 3, the other end of wireway 2 is connected with step glass tube 5 stub ends, and the microcephaly of step glass tube 5 is held and inserts funnel 6, utilizes basketball 4 as source of the gas, its effect: health, air-flow duration are long.Experimental result: table tennis also can not fall.Because the top gas flow rate of ball is fast, pressure is little; Ball below gas flow rate is slow, and pressure is large.
The utility model utilizes basketball as source of the gas in sum, and health, experiment are stablized, and the duration is long.Basketball replaces mouth to blow, and the relation of reacting fluid pressure and flow velocity intuitively can also excite the interest of Students ' Learning physics, while safety and sanitation, prevents transmission.
Claims (1)
