This value <br />should equal the residual pressure specified by the user unless the max velocity of 12 f /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 />MaD of Location <br />ws°s�si 1815 1r831 11206 i r' °, CIO, <br />�i N Nivs, <br />Zrssi5 1ws+0is8 -•�'�$ DG#13� xrsys��' J <br />I� 2 BLDG yp g r #14 zsues <br />SN <br />-s 2vn SLcoOG#6w522 node deled..9j^� 2' <br />Bt <br />�is oon ss vs ws2s 1�21 z `vs .
