Indirect....
I will skip the calculations and maybe point you a little different direction to research if all else fails. Of course, I don't know your specific application so I don't know if this will help.
Flow can be calculated when flow is through a known size orfice (assume pipe ID for...
Sorry for my previously short post,
shirsch makes a good point.
I will typically break a large pipe model into a single pressure zone. To do this you should have real operational data for the pressure zone breaks ie.. PRV's or Boosters. Also, you should have recent flow test data at several...
I have had a similar problem using old water cad files too. In my case, I had to verify element sybology colors and verify colors in "options" menu (fore ground & back ground colors) also.
I am trying to determine what advantages and/or disadvantages there are when using round or square (rectangular) wet wells for a plant influent lift station.
You may be able to set up seperate senerios where 1/2 of your model can be "shut off" or not active. I don't think Water CAD counts inactive pipes and nodes. To open the water cad .wcd, under file menu, find import water CAD database. try that.
