CITY OF EVERETT PUBLIC WORKS DEPARTMENT <br /> FIRE FLOW REPORT FORM (scenario 8) <br /> replace existing 6"with new 8"under SE Everett Mall Way,new 8"loop around edges of property <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) @Hydrant Pressure(psi) <br /> (gpm) (psi) (psi) fanm) <br /> - <br /> 1610 SE Everett Mall Way 528 FJ421 0 63 0 0 1540 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 /> sit, <br /> Qv <br /> 4NE 11ifT!'"::-., (,(a <br /> lSE <br /> \ / `V, / <br /> D� 45DEO b,»/ �'/ Whew <br /> s ' • -in <br /> amuu£D}} <br /> EO r 4 •;, /,, <br /> losed valve j9 , new 8 loop <br /> 7610 <br /> �/ <br /> ' r node modeled'(FJ421) <br /> - ` <br /> 1606 — --" <br /> i 4 �� 16 <br /> 02 = <br /> Y <br /> / x`1 ,.-� <br /> tiau i 1602 r"' <br /> ` ` <br /> c \ <br /> YYX :',otl_ J�-�. <br /> wD,t 1 <br /> L_ , <br /> / <br /> \' <br /> ANe <br /> ./_.
