Pitot Tubes Pitot tubes can be used to measure fluid flow velocity by measuring static and dynamic pressure difference Sponsored Links.

Static Pressure The first term - p - is the static pressure. The Pitot Tube The pitot tube is a simple and convenient instrument to measure the difference between static, total and dynamic pressure or head. Since you mentioned an excel format, I have also attached a crude copy of a flow curve generated for a particular set of flowing conditions. You only need to pull certain info from your flow calc. C' will be unique to the manufacturer , plug it into the excel program, and a curve with data points will be generated.

Since this forum is non-commercial, I have blacked out certain information on my attachments. Any avg. You should not have to generate a program yourself. Just make certain that the corresponding flow coefficient for YOUR averaging pitot is used in your calculation. There are many avg. Sorry I caught onto this link late. Hope this is helpful. Jake, much obliged for the guidance and info. Having spoken with a couple of our vendors, they then made me aware of their website calculators for the annubars.

Best regards, Danny. Is this Averaging pitot tubes or conventional pitot tube? Averaging pitot tube preferred with a conventional pitot tube cause it is difficult to determine the location along the pipe's diameter where the "impact opening" measuring fluid pressure plus velocity head should be located.

However, it is also suitable for velocity measurement of air flow in a rectangle and round channels. With a Prandtl probe, you can measure flow velocity indirectly, by measuring a difference between stagnation pressure and static pressure of flow in a single point of a flow streamline. A Prandtl probe measures stagnation pressure in the central part of a Prandtl probe, where flow velocity equals zero. When flow velocity is zero at some point of streamline, measured pressure in that point equals total pressure.

On the outer part of the Prandtl probe where flow streamlines are tangent to the Prandtl probe, the flow velocity is unimpaired, and the pressure measured at that part of streamline is called static pressure.

The difference between stagnation and static pressure in one point of flow streamline is called dynamic pressure. Dynamic pressure represents kinetic energy, and flow velocity can be calculated using this calculator. You can use the calculator for Pitot tube as well.

For supersonic flow a shock wave forms in front of the Pitot tube, and the pressure and temperature measurements must be compensated. The upstream and downstream flow is assumed to be isentropic.

The shock wave is adiabatic and non isentropic. Use the [FREE] tools in free basic mode with no login, or login to use the tools in free plus mode with plots, tables, goal seek etc.
