CALCULATING VOLUMES WITHIN A PIPEWORK SYSTEM
CALCULATING VOLUMES WITHIN A PIPEWORK SYSTEM
(OP)
Hi All.
Does anyone have a useful method of calculating voulmes within a pipework system?.
We use pro-pipe here and I have an assembly with pipework routing through components such as heat exchangers and vessel tanks.
My manager has asked me if I can calcuate the approximate volume of water within the system by using proe data, but all I can achieve is the "solid valume" of each part, ie not the hollow sections where the water will run.
Anyone got any tips or tricks?

if you know the volume of the pipe as a solid now
resize your O.D. to the current I.D. and subtract

Bearing in mind that pipes have wall thickesses I can only see this method working if the id = 0 which is probably not possible?

I don't have a solution right away, but my first idea is to compare the actual volume with a new volume where the inner space/air is removed.
So, how do you calculate the new volume with space removed?
An idea would be to use shrinkwrap, but a short test I did, was not working. Perhaps you can make it work.
Another idea is to copy all outside surfaces and then make them solid.
You then subtract the new outside volume with the actual volume.
I hope this is helping you.

If each part ends up with a commonly named parameter (i.e. FLUID_VOL), you can create a table in your drawing that has a repeat region summation to add all of these values together.

Embed the assembly in a solid block and boolean subtract it from the block. This'll leave you, after a little whittling, with two solid bodies; one of which is the system volume.
