The velocity pressure is recorded with a pitot tube and a gauge. This pressure is called which of the following?

Explanation:
Velocity pressure is dynamic pressure, the part of the fluid pressure tied to motion. A Pitot tube measures total (stagnation) pressure and static pressure; the difference between them is the velocity pressure, which corresponds to the kinetic energy of the moving air and can be expressed as 1/2 ρv^2. Flow describes how much volume moves per unit time, not a pressure, and static pressure is the pressure present without regard to motion. So the velocity pressure read by a Pitot tube is dynamic pressure.
