Question

bernoullis principle concerns the flow of a fluid through a/an
______ tube.

○ venturi
○ convergent duct
○ divergent duct

Explanation:

Bernoulli's principle is often demonstrated and applied using a Venturi tube, which has a constricted section (venturi) to show the relationship between fluid velocity and pressure. A convergent duct only narrows, and a divergent duct only widens, but the Venturi tube has a specific throat (constriction) followed by expansion, which is key for Bernoulli's principle applications in fluid flow.

Answer:

A. venturi
