CITY OF EVERETT PUBLIC WORKS DEPARTMENT <br /> FIRE FLOW REPORT FORM <br /> Project: Unknown <br /> Location: 5000 Blk Colby Ave. <br /> Date of Report: October 31,2017 <br /> Demand Conditions: Build-Out Max Day -Steady State <br /> Prepared By: Mike Mendlik <br /> Existing Structure ❑ Future Development E <br /> Static Static Residual Available <br /> Location Elevation Model node ID# at Demand Pressure Test Flow Pressure Flow Residual <br /> (ft) location (gpm) (psi) (gpm) (psi) @Hydrant Pressure(psi) <br /> (qpm) <br /> 5000 Blk Colby Ave. 320.43 16552 5.7 65 - 0 815 20 <br /> Explantion of Column Headings: i <br /> - — .6 -000) <br /> Location-the location of the current project ' I J <br /> Elevation-the ground elevation at the node,as referenced to the NAVD 88 datum .4/1V2t.v\ <br /> Model node ID#-the hydraulic model identifier L /A ��� <br /> Static Demand-The baseline demand at the specified node. v C <br /> Static Pressure-The calculated pressure for the static demand. <br /> LeAl- <br /> Test Flow-The maximum flow that is available while maintaining the user-specified minimum residual pressure and -e\r- J <br /> max flow velocity of 12 ft/sec at the current node,assuming that only this hydrant(node)is flowing. / ``\ <br /> \ro <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 fUsec 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 /> jj \'jft Inii11111 1. °s 1503 4• -- t; <br /> i <br /> A 0, <br /> L N"° S :18: i <br /> i x T° 4 <br /> i__ 50TH ST 9E _..__•4M_.°1°y \• t .
