With MEPCAD (AutoSPRINK) we can set each piece of pipe to be wet or dry; then you select the pipe and ask it to show pipe volumes. It will only show the volumes of the selected pipe and will separate wet and dry. To be sure you have all of the pipe set right, simply select all that is supposed to be dry and it should show only dry volume and vice versa for wet.
So easy and nice. Bobby Gillett Sr. Project Manager Key Fire Protection, Inc.

Always size to the actual system pipe volume. This will be different from the gpm required in the calc, and I have found with both SprinkCAD and HydraCAD (don't know about MEPCAD or any others since I haven't worked with em) that the system volume given needs to be checked. They both provide an answer, but not necessarily always an accurate one.
