CITY OF EVERETT PUBLIC WORKS DEPARTMENT <br /> FIRE FLOW REPORT FORM <br /> Project: Unknown <br /> Location: 7505 Hardeson Rd <br /> Date of Report: December 15,2007 <br /> Demand Conditions: Build-Out Max Day -Steady State <br /> Prepared By: Mike Mendlik <br /> Static Static Residual Available <br /> Elevation Model node ID# Test Flow Flow Residual <br /> Location Demand Pressure Pressure <br /> (ft) at location (gpm) (psi) (gpm) (psi) @Hydrant Pressure(psi) <br /> (gpm) <br /> 7505 Hardeson Rd 496.75 11038 13.6 89 1,514 70 1,878 62 <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 <br /> and 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 <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 /> may/ � I `;," 1 <br /> Iwe <br /> nods modeled `' <br /> •..4+/// i.e <br /> A - Fo-- . <br /> WS Ml E' D1 -m20 <br /> 7501 Fs ;7 --. �150: <br /> �.
