E CITY OF EVERETT PUBLIC WORKS DEPARTMENT <br /> FIRE FLOW REPORT FORM (scenario 1) <br /> existing conditions <br /> Project: Unknown <br /> Location: 1610 SE Everett Mall Way <br /> Date of Report: August 20,2012 <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) (psi) (gpm) (psi) @Hydrant Pressure(psi) <br /> (aDm) <br /> 1610 SE Everett Mall Way 528.00 FJ421 0.0 63 - 0 1,460 20 <br /> Explantion 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 /> pressure and max flow velocity of 12 ft/sec at the current node,assuming that only this hydrant(node)is <br /> Residual Pressure-Residual pressure calculated for the available flow at the current hydrant(node).This <br /> value should equal the residual pressure specified by the user unless the max velocity of 12 ft/sec is the <br /> 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 /> Map of Location <br /> Qzoti?' /1 / j <br /> r <br /> 6]I 8'RED , // <br /> / // r 1 <br /> / node modeled (FJ421) <br /> / 161G <br /> 4'' <br /> / III <br /> /...,, <br /> , _ _ <br /> 1505 1608 1802 <br /> rs ais <br /> 2' J.: ti ala /../ !/ 1802 �._.� <br /> �C `a.
