Bernoulli Principle Apparatus STEM Lab Manufacturer,Supplier and Exporter in India
Product Code : SCL-MH-12498
Quick Answer: The Bernoulli Principle Apparatus blows air from a variable-speed 12V DC micro-blower through a transparent acrylic Venturi tube. A built-in 3-column water manometer shows the pressure falling where the tube narrows and the air speeds up.

About This Product
Comparing the manometer columns at the wide and narrow parts of the Venturi tube shows students that faster-moving air has lower static pressure, and lets them check the continuity relationship between cross-section and speed. Swapping in the wing section shows the pressure difference that produces lift, while the floating sphere links the same idea to aircraft, atomisers and chimney draughts.
Frequently Asked Questions
How are the manometer columns prepared on the Bernoulli Principle Apparatus?
Fill the vertical columns with distilled water up to the zero line and make sure no air bubbles are trapped in the connecting tubes.
What attachments come with the Bernoulli Principle Apparatus?
An airfoil wing section with surface pressure ports and a suspension nozzle with lightweight spheres, in addition to the Venturi tube.
