| CALC : Flow : Bernoulli 051 : Pitot Tube Velocity - From Pressure : Calculator
Description : Calculate the fluid velocity from the pressure difference in a Pitot tube.
Discussion : Pitot tubes are commonly used to measure the velocity of power boats. Pitot tubes measure the the pitot pressure (the sum of static and dynamic pressure). The fluid velocity can be calculated from the pitot pressure provided that the static pressure of the fluid is negligible. On boats the pitot tube is mounted close to the surface of the water so that static pressure effect is small. Constant static pressure can be compensated for by the instrumentation.
