The Results Table 1 The results of the hydraulic calculation for crane workshop The figure of density/Area Cruves is as follow:įigure 1 Density/Area Curves 2.6. Where: ΔP= difference of pressure in bar pm= frictional resistance in bar per meter of pipe L= length of Pipe in m Le = equivalent length in m ΔH= difference of level in m. Difference of Pressure P  pm ( L  Le )  H /10 Where: pm= frictional resistance in bar per meter of pipe Q= flow in L/min C= friction loss coefficient, for galvanized steel pipe of this project, C=120 dm= actual internal diameter in mm.

Frictional Resistance Pipe friction losses shall be determined on the basis of the Hazen-Williams formula, as follows: Where: V=flow rate in m/s Q= flow of pipe in L/min Di= internal diameter in mm 2.4. Where: q= flow of node in L/min Kp= K-factor, for this project, Kp=80 p=pressure of point in bar. Flow of Node Pressure balancing shall be permitted through the use of a K-factor developed for branch lines or portions of systems using: 1.0 bar will be adopt as the extreme pressure point at the remotest of the pipe in this design. The Extreme Pressure Point According to requirements of NFPA 13-2007. HYDRAULIC CALCULATION OF SPRINKLER SYSTEM 2.1. 3) BS EN 103 Plastics Piping Systems for Water Supply-Polyethylene (PE)Ģ. Codes and Standards 1) NFPA 13-2007 Standard for the Installation of Sprinkler Systems 2) ASME B36.10M-2004 Welded and Seamless Wrought Steel Pipe. 3) HDPE pipe (meets the requirements of BS EN 103 Plastics Piping Systems for Water Supply-Polyethylene (PE) ) is adopted as the buried pipe in fire fighting system. Standard (STD) wall thickness is adopted as the wall thickness of the pipe in this design. 2) Galvanized steel pipe (meets the requirements of ASME B36.10M-2004 Welded and Seamless Wrought Steel Pipe) is adopted as the sprinkler system of this design. General 1) This hydraulic calculation of sprinkler system is for crane workshop of Pakistan Deep Water Container Port. 3 ANNEX A.ĭETAIL HYDRAULIC CALCULATION OF SPRINKLER SYSTEM.
