CITY OF EVERETT PUBLIC WORKS DEPARTMENT <br /> FIRE FLOW REPORT FORM (scenario 7) <br /> replace existing 6"with new 8"under 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 /> (aom) <br /> 1610 SE Everett Mall Way 528 FJ421 0 63 0 0 1555 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 /> Ma•of Location <br /> r.,••;:.'7'- <br /> 77 DEG ., / �'� <br /> i `Aiew : main <br /> 17DE• l <br /> a <br /> <` Alb", node modeled (FJ421) <br /> �3 •• EG <br /> % / 610 <br /> / <br /> /WS R1 <br /> 3N• <br /> N / <br /> 1505 , 8j 1606 —j. 1602 <br /> Ws we `.� '.,,,/: <br /> �/ `�^/ <br /> T / m MJ / / 1602`- _ !`_. — _ <br /> �, / 7, -_ <br /> C W308/ <br /> x,•R@gumasrh• - / �• • .% EAST MALL DR <br /> A.02 %' Q' '--J �w1•sM <br /> / <br /> 11' �� O�� ;��� WS Cal •1 152f1 <br /> — � • -- ' <br />
