09-12: A Reynolds Number Correction for Pitot Measurement Miscellaneous

09-12: A Reynolds Number Correction for Pitot Measurement MiscellaneousThe Pitot tube has been the mainstay of flow measurement in cooling towers for decades, but this isn't the only application for velocity probes of this type. Unlike the cooling tower flow, most other applications of these and similar probes consider the Reynolds number typically at the head of the probe. The correction for Reynolds number in the derived correlations for such probes is iterative, but easily implemented and converges quickly. The

Our evaluation of this novel approach was based on laboratory data and on data generated in operating systems where reducing contaminants and iron deposition have limited the effectiveness of conventional chrome-zinc programs

Another is the use of blended polymers

This provides important information regarding the fate of the material in the system as well as the suitability of the biocide feed protocol selected

there are still many failures due to corrosion of yellow metals

The paper will discuss recent innovations in solid biocides and the numerous advantages over their liquid counterparts
