A zwitterionic and a cationic surfactant were compared concerning their effectiveness in drag reduction. Both reach even lower friction factors than can be determined by the known maximum drag reduction asymptote in polymers. It is shown that both the maximum effectiveness and the range of surfactant activity depend not only on the temperature and concentration of the solution, but also on the length of the direct entering section and on the quality of water. The influence of the particular locality of the flow rate regulation is also notified.
