<br /> FIRE FLOW REPORT FORM (scenario 10)
<br /> add new hydrant at NE corner of property
<br /> Project: Bob's Burgers
<br /> Location: 1605 SE Everett Mall Way
<br /> Date of Report: October 16,2009
<br /> Demand Conditions: Build-Out Max Day -Steady State
<br /> Prepared By: Mike Mendlik

<br /> 1605 SE Everett Mall Way 530 new node 0 49 0 0 677 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.
