<div class="textblock"><p><b>Purpose:</b></p>
|
|
<p>Defines data curves and their X,Y points.<br />
|
|
</p>
|
|
<p><b>Format:</b></p>
|
|
<p>One line for each X,Y point on each curve containing:</p><ul>
|
|
<li>Curve ID label</li>
|
|
<li>an X value</li>
|
|
<li>a Y value</li>
|
|
</ul>
|
|
<p><b>Remarks:</b></p><ol type="1">
|
|
<li>Curves can be used to represent the following relations:<ul>
|
|
<li>Head v. Flow for pumps</li>
|
|
<li>Efficiency v. Flow for pumps</li>
|
|
<li>Volume v. Depth for tanks</li>
|
|
<li>Head Loss v. Flow for General Purpose Valves</li>
|
|
</ul>
|
|
</li>
|
|
<li>The points of a curve must be entered in order of increasing X-values (lower to higher).</li>
|
|
<li>If the input file will be used with the Windows version of EPANET, then adding a comment which contains the curve type and description, separated by a colon, directly above the first entry for a curve will ensure that these items appear correctly in EPANET's Curve Editor. Curve types include <b>PUMP, EFFICIENCY, VOLUME</b>, and <b>HEADLOSS</b>. See the examples below.</li>
