&lt;p&gt;&lt;/p&gt;
&lt;p&gt;I am modelling a wastewater transfer line in Hammer. When I tried to calculate the wave speed I found that the wastewater is not among the available liquids in Liquid Library.&amp;nbsp;&lt;/p&gt;
&lt;p&gt;And my Liquid Library is locked!&amp;nbsp;&lt;/p&gt;
&lt;p&gt;&lt;/p&gt;
&lt;p&gt;Thank You!&lt;/p&gt;

Different pipe sizes are used in the model for the pump station and transfer line (a range of 6&amp;quot; to 24&amp;quot;)&lt;/p&gt;
&lt;p&gt;In the initial conditions run I get the message&amp;nbsp;of low pressure points in the model.&lt;/p&gt;
&lt;p&gt;When I compute the transient it shows the Engine Error Message as attached.&lt;/p&gt;
&lt;p&gt;So, I removed the pipeline after the high elevation point and the error of low pressure points and Engine calculation failure are removed.&lt;/p&gt;
&lt;p&gt;But How Can I solve the model for water hammer with keeping the whole line?&lt;/p&gt;
&lt;p&gt;&lt;/p&gt;
