CITY OF EVERETT PUBLIC WORKS DEPARTMENT <br /> FIRE FLOW REPORT FORM (scenario 3) <br /> new 8"main North to apartment complex <br /> Project: unknown <br /> Location: 1605 SE Everett Mall Way <br /> Date of Report: June 9,2011 <br /> Demand Conditions: Build-Out Max Day -Steady State <br /> Prepared By: Mike Mendlik/✓ <br /> di.d/ <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) Hdrant Pressure(psi) <br /> , —(a-pm) <br /> 1605 SE Everett Mall Way 525.00 7162 0.0 67 - 0 2,757 22 <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 /> � I I , 1, ir. , <br /> -aro BLDG f B[IO 41° I a i aio s [ <br /> 1 I • ' -.1 ! � �OOo0G0IB 1—�l --J a `\ <br /> # <br /> r <br /> I.. rf,3"main <br /> ----.. /, -: <br /> L <br /> 1 --�J l _ _ I -- % <br /> 1)I 100° iG I // /// <br /> i fL / j//,/ <br /> V % i/% ; <br /> —_ //'1 7;/�/, <br /> j <br /> 47/4.42///. 7- <br /> �7� <br /> I r,-..J.,ra atll'- i7-182j / ' -'y'. / / <br /> — <br /> ma A >sos ��,// " 7---'.. <br /> m, /.." 10231023\` \\'/ - f }J aa.
