CITY OF EVERETT PUBLIC WORKS DEPARTMENT <br /> FIRE FLOW REPORT FORM (scenario 6) <br /> replace 6"main on southern edge of SE Everett Mall Way with 8", new 8"main to W Mall Dr <br /> Project: Bob's Burgers <br /> Location: 1605 SE Everett Mall Way <br /> Date of Report: October 16,2009 <br /> Demand Conditions: Build-Out Max Day -Steady State <br /> Prepared By: Mike Mendlik <br /> Static Static Residual Available <br /> Location Elevation Model node ID# Demand Pressure Test Flow Pressure Flow Residual <br /> (ft) at location (gpm) @Hydrant Pressure(psi) <br /> (gpm) (psi) (psi) <br /> loom) <br /> 1605 SE Everett Mall Way 525 7162 0 52 0 0 1451 32 <br /> Exglantion of Column Headings: <br /> Location-the location of the current project <br /> Elevation-the ground elevation at the node,as referenced to the NAVD 88 datum <br /> Model node ID#-the hydraulic model identifier <br /> Static Demand-The baseline demand at the specified node. <br /> Static Pressure-The calculated pressure for the static demand. <br /> Test Flow-The maximum flow that is available while maintaining the user-specified minimum residual pressure and <br /> max flow velocity of 12 fUsec at the current node,assuming that only this hydrant(node)is flowing. <br /> Residual Pressure-Residual pressure calculated for the available flow at the current hydrant(node).This value <br /> should equal the residual pressure specified by the user unless the max velocity of 12 ft/sec is the constraint. <br /> Notes: <br /> 1) All elevations are given in reference to the NAVD 88 vertical datum <br /> 2) The pressure(in psi)at a node is obtained by subtracting the nodal elevation from the hydraulic grade line and dividing by 2.308. <br /> 3) The data given are valid only for the location,elevation,and conditions noted. Use of this data at other locations must account for <br /> elevation differences and for frictional losses <br /> 4) Flow data will change in response to future changes in the water system configuration and future changes in water demand. <br /> Ma.of Location <br /> ifiz <br /> r 'a node modeled(71¢ j <br /> new 8"main , <br /> r'i I <br /> ' /-1-1 / L___r_;.,.. 1—, IP - <br /> [ t i= :1lLSI kx \ <br /> ;r,.l. <br /> 11 j` <br /> I <br /> 1 <br /> \ -__ °.` w 8 main -`- <br /> ne ° <br /> r 1 <br /> lo ,./.. <br /> ---,...,,,,„ . <br /> .. <br /> I. <br /> " <br /> 1. .,X` �" <br />
