Name: Demonstration of the relationship between fluid flow rate and pressureMaterial: PVCSize:11*23.5cm/4.33*9.25 inlist:1. One piece of fast and slow flow tube.2. Two U-shaped tubes3. One teaching board4. Several latex tubesInstructions1. First drop the pigment aqueous solution into the U-shaped tube2. The shape of the fast and slow flow rate tubes is thin and then thick and then thin, so when there is airflow (just blow it with your mouth) into the tube, the flow rate of the thin part is fast, and the flow rate of the thick part is slow. The pigmented surfaces in the U-shaped tube form a pressure differential. From the scale on the teaching board, you can see how many grids the pressure difference is.
★The model is an intuitive teaching aid for physics teaching
★The instrument can scientifically and intuitively demonstrate the relationship between fluid pressure and flow rate to students.
★Let students know that the pressure is low when the flow rate of the fluid is fast, and the pressure is high when the flow rate of the fluid is slow.
★Improve students' interest in science
★We attach great importance to customer experience, if you have any questions, please contact us, we will reply you within 24 hours!
