Where can the discharge coefficients Cv be obtained?

The discharge coefficients Cv can be obtained from the standard (ISO 5167) for nozzles, Venturi tubes and orifice plates that are manufactured to the specified tolerances of the standard.

What are the advantages of pitot tubes?

Pitot tubes are simple to use and install. They operate trouble-free with a constant performance and have practically no pressure drop. With pitot tubes, a cost effective measurement and energy saving is possible. They can be used either as a permane ...
