Which of the following parameter can be measured using venturi?

(a) temperature

(b) velocity

(c) volume

(d) density

I had been asked this question in semester exam.

My doubt stems from Incompressible Flow in Duct topic in portion Inviscid & Incompressible Flow of Aerodynamics

The correct answer is (a) temperature

For explanation: Using venturi, velocity can be measured. We can calculate the pressure difference using venturi. In the duct, we can place pressure gauge which will directly give us the pressure difference (p2-p1). This pressure difference can be related to velocity using Bernoulli’s equation and hence, the velocity can be calculated.
