• CITY OF EVERETT PUBLIC WORKS DEPARTMENT <br /> FIRE FLOW REPORT FORM (scenario 6) <br /> new 8"main on South edge of SE Everett Mall Way <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 /> (Qom) <br /> 1610 SE Everett Mall Way 528 FJ421 0 63 0 0 2543 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 /> Test Flow-The maximum flow that is available while maintaining the user-specified minimum residual pressure and <br /> max flow velocity of 12 ft/sec 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 /> Map of Location <br /> I <br /> / /9/ <br /> ;%/ <br /> / , . ,�, node modeled(FJ421) <br /> % c <br /> —. <br /> / <br /> MI <br /> \ <br /> II,SII.11 111 _.1J /� • M: \ <br /> -*" new a main % �� <br /> r. <br /> _ '7,..71.="' <br /> /// <br /> __ _ ill ...,, <br /> /// <br /> If ,1 if , <br /> f <br /> (.... lL <br /> ..1.21I <br /> f <br />
