About this document
Pitot Tube Fluid Velocity Measurement by Sean Gallego is a document available to read on EtoBox.
Pitot tubes measure fluid velocity by determining the difference between stagnation pressure and static pressure. Stagnation pressure is measured perpendicular to flow and includes velocity pressure, while static pressure is measured parallel to flow. The difference between these pressures (ΔP) can be used to calculate velocity according to the equation V = (2ΔP/ρ)1/2, where ρ is the fluid density. An example calculation demonstrates using a pitot tube measurement in a duct to determine the air velocity is
