A discharge rating curve for the intake is provided in Fig. 12. Flow conditions through the transition were satisfactory for all discharges. An air went should be provided in the conduit at a distance of 40 feet to 80 feet downstream from the transition, The exact location to be determined from the general location of the intake in relation to Logan Street. Velocity profiles in the conduit indicate that no u usual conditions prevail. The model construction tests and conclusions and recommendations are described in this report.reportsengCopyright and other restrictions may apply.
