While using Netsys Heating or Chilled water it may be noted that the pressure drop for pipe sections exceeds the maximum pressure drop provided through the system marker.
The software follows these methods during sizing:
Ingram - I cannot confirm - 2003/2004 would represent either version 19 or version 20 of the software. While I do have version 23 installed - and I confirm that it exists there - I can only suggest creating a project and checking the Defaults option on the Pipes menu to see if it exists. If you running the Legacy version of Netsys, then I would suspect that it does not exist there.
