Static Pressure - The calculated pressure for the static demand. Test Flow - The maximum flow that is available while maintaining the user -specified minimum residual pressure and max flow velocity of 12 ft/sec at the current node, assuming that only this hydrant (node) is flowing. Residual Pressure - Residual pressure calculated for the available flow at the current hydrant (node). This value should equal the residual pressure specified by the user unless the max velocity of 12 ft/sec is the constraint. Notes: 1) All elevations are given in reference to the NAVD 88 vertical datum 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. 3) The data given are valid only for the location, elevation, and conditions noted. Use of this data at other locations must account for elevation differences and for frictional losses 4) Flow data will change in response to future changes in the water system configuration and future changes in water demand. of Location
