VENTURI PIPE

thingiverse

This object was carefully designed and printed by high school students aged 14-15 from the (Name) Secondary School as part of the PRINT STEM project, funded by the Italian National Agency INDIRE through the Erasmus+ program www.printstemproject.eu. Bernoulli's equation is a fundamental principle that connects speed, pressure, and height in a fluid flowing without rotation. The Venturi Tube is an iconic demonstration of Bernoulli's equation, illustrating how pressure changes with fluid speed. To achieve this effect, students were tasked with creating a model of the Venturi Tube using 3D printing technology. The tube was printed vertically to avoid supports, and the side holes were drilled into place. Print Settings: * Printer Brand: Deltaprintr * Printer Model: Deltaprintr Assembled * Rafts: Yes * Supports: No * Resolution: High * Infill: 100% Design Notes: The tube should be printed vertically to prevent support material from obstructing the design. The side holes were drilled into place using a drill bit. Post-Printing Exercise Ideas: 1. Verify Bernoulli's equation by measuring pressure and speed in the Venturi Tube. 2. Determine the fluid speed required for negative pressures to occur in the tube. 3. Develop methods to measure negative pressure in a Venturi pipe like this one. Design Process: I used AutoCAD software to design and create this 3D model of the Venturi Tube.
