- Abstract:
- For the measurement of velocity of gas streams in ducts, the S pitot tube is one of the most widely used velocity measurement devices. Factors as Reynolds number and misalignment can be additional error sources for the S pitot coefficient. The variation of S pitot coefficient is observed on five different manufactures of S pitot through the airs peed standard system. The results of these experiments indicate that the coefficient curve of S pitot tube is fluctuated at small velocities around 0.2 % up to 0.7 %. The coefficient value of S pitot tube has a band from 2 % to 4 %
