Total and dynamic pressure are not pressures in the usual sense – they cannot be measured using an aneroid, Bourdon tube or mercury column. Stagnation pressure is sometimes referred to as pitot pressure because it is measured using a pitot tube. Velocity can be determined using the following formula: A Pitot tube is a pressure measurement instrument used to measure fluid flow velocity.u is flow velocity to be measured in m/s.p s is stagnation or total pressure in Pa.Fundamentals of Heat and Mass Transfer, 7th Edition.Fundamentals of Heat and Mass Transfer.

Physics of Nuclear Kinetics. Addison-Wesley Pub.As shown in Figure 13, the pitot tube is a tube within a tube. Flight data such as airspeed, altitude, and rate of climb stems from the pitot tubes and associated systems. Because air is considered a fluid in physics, aircraft use a pitot tube as a sensor that provides vital data necessary for a safe flight by measuring air pressure. The 'Pitot Tube' is named after the French physicist Henri Pitot. A pitot tube is an instrument used to measure the velocity of a flowing fluid. A single hole with a pitot tube and manometer can be used to measure the velocity pressure. Robert Reed Burn, Introduction to Nuclear Reactor Operation, 1988. It is not necessary to drill two holes in a piece of duct work to measure velocity pressure. The pitot tube is used to measure the local flow velocity at a given point in the flow stream and not the average flow velocity in the pipe or conduit.
