Question

The correct assumption(s) made to perform a venturi-meter experiment is(are):

• A. that Bernoulli's theorem holds good
• B. that equation of continuity is maintained
• C. that the fluid used is highly incompressible
• D. that all of the above are true

Answer 1

Answer: (D)

that all of the above are true

Venturi-meter is a device used to measure the rate of flow of a liquid through pipes .Its working is based on Bernoulli's principle. To get the rate of flow of a liquid in a pipe by a Venturi-meter, both Bernoulli's theorem and equation of continuity are used and we know that equation of continuity works when the liquid is considered as incompressible (so that, its density doesn't change anywhere in its path of flow).

Hence, all the given assumptions are true.
