CITY OF EVERETT PUBLIC WORKS DEPARTMENT <br /> FIRE FLOW REPORT FORM (scenario 3) <br /> New 8"main on north edge and crossing under SE Everett Mall Way <br /> Project: Unknown <br /> Location: 1610 SE Everett Mall Way <br /> Date of Report: October 10,2012 <br /> Demand Conditions: Build-Out Max Day -Steady State <br /> Prepared By: Mike Mendlik <br /> .�/ <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 /> (aom1 <br /> 1610 SE Everett Mall Way 528.00 FJ421 0.0 63 2,200 29 2,302 26 <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 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 /> ri.w+P En.ft / <br /> Lo11 Coil/ <br /> ''' ir./. <br /> i <br /> new8" main %f <br /> BOD- <br /> NN . <br /> , ;�. node modeled (FJ421) <br /> (////:,,.. ,°.',,./:-44,4,. <br /> ' .� 1610 <br /> t • <br /> /• 1646 <br /> e rte..-- —_...------- <br /> ....- <br /> 41! <br /> 1802 <br /> 1505 / '� � �` -'" _ __ <br /> _s ute �� \�`�_ <br /> \ ' > u<ou ,� / 1602 / ^__ ---------- <br /> ' <br /> `- -_ f---�_�---�"_ f-- <br /> 0' jL1016 1 _ l f <br /> �� � S - .ill <br /> � / � e k ow rPs uta/• <br /> US ��'✓- moi'-. <br /> e- / <br /> WS oz 3 j PRF �p <br /> Ps • of:,/ �.
