Influencing factors to the friction charging in water delivery metal pipeline

The circulation flow chart of the friction charging in the water delivery metal pipe. The circulation flow chart presents the essential experimental facilities for water delivering. The Keithley Model 2450 SourceMeter® was used to measure the voltage and current generated by the friction motion in the test pipe with different kinds of waters. The flow rates and the installing of an electric charge trapper in the pipe would influence the electrochemical reaction and the corrosion process.161
