Hydrogen Bubble Technique

The hydrogen bubble technique for flow visualization is modified for quantitative determination of velocity of water flowing in clear plastic tubes. Calibration tests are reported showing the accuracy which may be expected of the technique. The technique is verified by application to the determination of the hydrodynamic entrance length in steady flow.
