About this file
This document is a Hydraulic Calculation Analysis for the existing fire sprinkler system at the VA Dallas Building FP1. The analysis shows the existing system with K5.6 sprinklers is not capable of providing the required 0.23 density over 2000 SF, excluding in-rack sprinklers. The document recommends replacing the existing K5.6 sprinklers with new K11.2 high-temperature upright CMSA sprinklers throughout the warehouse area of Building #1. It also calls for abandoning the existing riser, adding a new 8" system riser/zone to the existing pump house, and installing a 4" bulk main to connect to the existing 4" cross-main. The goal is to provide adequate flow and reduce friction loss to meet the new design criteria. The document provides detailed hydraulic calculations, fitting legends, and node summaries related to the existing and proposed sprinkler system modifications.

Note: Fitting Legend provides equivalent pipe lengths for fittings types of various diameters.
Equivalent lengths shown are standard for actual diameters of Sched 40 pipe and CFactors of 120 except as noted with *. The fittings marked with a * show equivalent lengths values supplied by manufacturers based on specific pipe diameters and CFactors and they require no adjustment. All values for fittings not marked with a * will be adjusted in the calculation for CFactors of other than 120 and diameters other than Sched 40 per NFPA.
