How does Hevacomp calculate this and what value does it use for the specific heat capacity of water?</p> <p>We get the volume flow rate to be&nbsp;16,065 / ( 4.186 * 8.4 ) = 456.88 l/s.</p><div style="clear:both;"></div>https://communities.bentley.com/products/building/performance/f/hevacomp-forum/114955/hevacomp-pipe-database-sizeTue, 12 Jan 2016 08:34:10 GMT6dad98f5-dbc9-4c4d-a9ba-e9da8dc6aa8e:1748a44a-27b8-4019-9f33-c21aa03bc4faThomas Nutt<p style="margin:0in 0in 0pt;"><span style="font-family:Calibri;font-size:medium;">We are having problem with the hevacomp software. There are no pipe sizes greater than 500mm in the software database. This is a problem as we have pipes installed within the systems we are trying to model which are 600mm and above. Can you please provide an updated database so that we can produce an accurate model?</span></p> <p><span style="font-family:Times New Roman;font-size:medium;"> </span></p><div style="clear:both;"></div>
