For friction loss data in accordance with the UL Certification, please refer to pages <br />19 and 20 of this publication. <br />How to use this Design Guide. <br />• For some systems, it may be advantageous for the designer to calculate the system hydraulics using shorter equivalent lengths associated with fewer than the <br />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 <br />from the design guide to determine the system hydraulics. <br />• 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 <br />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 <br />recalculated using actual equivalent lengths to verify the performance of the system. <br />10.85 5839Rev At Updated 02/2022 02022 Victaulic Company.
