The invention discloses a fluid pressure and flow velocity relation demonstrator and relates to a teaching apparatus. The demonstrator comprises three ventilating boxes different in size, three transparent round tubes (5) identical in diameter, demonstration balls (6), seal rings (4), a support (1), springs (7) and screws (10), wherein the three ventilating boxes are mutually connected together on the upper box surfaces through connecting plates (11), the lower sides of the three ventilating boxes are mutually connected through right-angled connecting pieces (15), the support (1) is mounted below the medium ventilating box (2) and is mounted on a demonstration table, an air inlet (3) is formed in one side of the medium ventilating box (2), and an air hole (16) is formed in the other side of the medium ventilating box (2). The fluid pressure and flow velocity relation demonstrator has the advantages that the demonstrator demonstrating the fluid pressure and flow velocity relation by gas helps students comprehend the fluid pressure and flow velocity relation, is convenient for a teacher to explain knowledge points and enlighten the students of application and flexibility of knowledge about the fluid pressure and flow velocity relation and particularly, can be applied to analysis on airplane lift reasons and the like.
Description
technical field [0001] The invention relates to a teaching instrument, in particular to a demonstrator for the relationship between fluid pressure and flow velocity. Background technique [0002] The relationship between fluid pressure and flow velocity is one of the key points of physics teaching in junior high school, and it is also one of the difficulties in teaching. Therefore, it is very important to do experiments on the relationship between fluid pressure and flow velocity and their characteristics. According to the survey, the experimental objects of the patented demonstration devices for the relationship between fluid pressure and flow velocity that have been applied for at present are all liquids, and the relationship between fluid pressure and flow velocity has not yet been found for special gas demonstration. Contents of the invention [0003] The object of the present invention is to provide a demonstrator for the relationship between fluid pressure and flow ...
