How to use this Design Guide: • For some systems,it may be advantageous for the designer to calculate the system hydraulics using shorter equivalent lengths associated with fewer than the maximum allowable number of bends.In this case,the designer may select a design number of bends for the job and use the associated equivalent length from the design guide to determine the system hydraulics. • It is possible that the actual installed condition of some of the flexible drops may have more bends than the designer selected.When this happens,the design guide may be used to find equivalent lengths based on the actual installed number of bends for particular sprinkler installations.The system hydraulics can be recalculated using actual equivalent lengths to verify the performance of the system. • 10.85 5839 Rev AL Updated 02/2022 ®2022 Victaulic Company.All rights reserved.
