✦ Synopsis

Longitudinal dispersion coefficients have been obtained for a dilute aqueous polymer system displaying drag reducing properties. The analysis and velocity profiles of Tichacek et al. are extended to describe the behaviour of this system, and good agreement with the theory is obtained. The measured dispersion coefficients for the polymer solution are as much as 30 per cent greater than those for water in the Reynolds number range 3000 to 30,000. Comparison is also made with analyses based on other velocity profiles.
