The velocity pressure recorded by a pitot tube and a gauge is known as

Explanation:
Velocity pressure is the part of a fluid’s pressure that comes from its motion. In a pitot-static setup, the pitot tube measures total pressure while static ports measure the fluid’s static pressure. The difference between these two pressures equals the dynamic (velocity) pressure, which is related to speed by q = 1/2 ρv^2. This dynamic pressure is what the gauge reads as velocity pressure. The term flow, on the other hand, refers to a rate of volume per time, not a pressure value, so it isn’t the correct label for this measurement.
