Problems solved by technology
[0003] However, most of the existing connector water flow measurement experiments use simple connectors to directly inject water for demonstration. The process is relatively simple and the demonstration effect is poor. During the measurement demonstration, only the change of the water level can be seen, but the pressure of the water flow and the display effect cannot be displayed intuitively, and it is not convenient to change the experimental variables to conduct multiple experiments, which is not conducive to students' deepening of understanding and memory

Description
technical field [0001] The invention relates to the technical field of teaching equipment, in particular to a water flow measurement system for physics teaching. Background technique [0002] In the process of physics teaching, some physical phenomena are selected to be operated by the experimental equipment, so that the teacher can demonstrate directly and the students can learn intuitively. Among them, the water flow measurement of the connector needs specific demonstration teaching. [0003] However, most of the existing connector water flow measurement experiments use simple connectors to directly inject water for demonstration. The process is relatively simple and the demonstration effect is poor. During the measurement demonstration, only the change of the water level can be seen, but the pressure of the water flow and the display effect cannot be displayed intuitively, and it is not convenient to change the experimental variables to conduct multiple experiments, which...
