This value <br />should equal the residual pressure specified by the user unless the max veocty 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 ciNerer,:es and for frictional losses <br />4) Flow data will Uonge in response to future changes in the water system configuration and future changes in water demand. <br />RmsAve <br />
