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 />e <br />node modeled (J118) <br />- e3oi <br />Y` V. .. <br />x...... <br />f' <br />
