Abstract
This utility model relates to a demonstrating device of fluid pressure and flow rate relationship, including a water pump, a blower, a back board, a glass tube, a water channel and a horizontal flow channel. The back board is installed with the water channel, and the glass tube is composed a tube A and a tube B which are connected on the horizontal flow channel; the position of connecting tube A and the flow channel is thinner than that is of the tube B, and one end of the horizontal flow channel is connected with a water pump; the glass tube and the horizontal flow channel are pasted on the back board, and the back board is drawn with scale line; the advantages are that this utility model is manufactured easily, teaching is easy to understand, and this utility model is used to culture the observation, analysis and problem solution capability.
Description
Technical field
The utility model relates to experiment teaching aid, particularly relates to the apparatus for demonstrating of fluid pressure and flow velocity relation.
Background technology
Tell about the relation of fluid and flow rate of fluid and fluid pressure in the physics, very abstract theoretically, draw the water of facing this every day, character and the mechanics that air has do not known, for strengthening sense organ understanding, the making apparatus for demonstrating experimentizes, and fully understands that flow velocity and hydrodynamic pressure relation are very necessary.
Summary of the invention
The technical problems to be solved in the utility model provides the relation that can demonstrate rate of flow of fluid and fluid pressure, and then increases the apparatus for demonstrating of understanding fluid pressure and flow velocity relation.
The technical scheme that adopts:
The apparatus for demonstrating of fluid pressure and flow velocity relation comprises water pump, hair-dryer, backboard, glass tube, tank, horizontal run.Described backboard and tank are fitted together, and glass tube is divided into the A pipe and B manages two, is connected on the horizontal run, and the runner place that the A pipe connects is thinner than the runner place that the B pipe connects, one end of horizontal run connects water pump, and glass tube and horizontal run all stick on the backboard, are decorated with scale mark on the backboard.
Simple, the straight difficulty of teaching that the utility model is made is cultivated observation of students, analysis and problem-solving ability.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
The apparatus for demonstrating of fluid pressure and flow velocity relation comprises water pump, hair-dryer, backboard 1, glass tube 2, tank 3, horizontal run 4.Described backboard 1 is fitted together with tank 3, glass tube 2 is divided into the A pipe and B manages two, be connected on the horizontal run 4, and the runner place that the A pipe connects is thinner than the runner place that the B pipe connects, one end of horizontal run 4 connects water pump, glass tube 2 and horizontal run 4 all stick on the backboard 1, are decorated with scale mark on the backboard.During experiment, water pump draws water, and the pressure that water enters horizontal run water advances A pipe and B pipe to hydraulic pressure, and it is high to observe A pipe water table ratio B pipe this moment, and it is thin that the A pipe connects the horizontal run place, and flow velocity is big, and conclusion is that the big position of flow velocity pressure is big.Described hair-dryer energising, wind is blowed to A pipe upper end with the 45 position then, A pipe upper end air velocity accelerates, and atmospheric pressure diminishes, and then water is emerged by upper port in the A pipe, and experiment finishes.
