Correct option is C
A
Pitot tube is a device used to measure the velocity of flow at a specific point in a pipe or channel. It works by measuring the difference between the stagnation pressure (total pressure) and the static pressure, which can then be used to calculate the velocity of the fluid using Bernoulli's equation.
·
Orificemeter: Measures the flow rate, not the velocity at a specific point.
·
Venturimeter: Also measures the flow rate, not the velocity at a particular point.
·
Manometer: Measures pressure, not velocity.
