Answer:

C

Explanation:

Pitot tube:

Pitot tube is a device which is used to measure the velocity of flow by measuring pressure difference between the points.

As we know that stagnation pressure is the summation of dynamic and static pressure.

Stagnation pressure = Static pressure + Dynamic pressure

So

Dynamic pressure = Stagnation pressure - Static pressure

We know that dynamic pressure

[tex]P_{dynamic}=\dfrac{\rho V^2}{2}[/tex]

On the other hand Pitot tube measure the dynamic pressure.

So option C is correct.
