I have some Piping spools that I would like to find the internal volume capacity. Does any one know how to find this without having to create a part that would fit inside the piping?
Thanks for your help guys. I actually thought of a method of my own. I created the spools using the routing add on. To calculate it I just measured the lines in the 3D sketch of pipe giving me the total lenth for each size. Then I just got the ID of the pipe and used the equation for the volume of a cylinder to figure the capacity of each spool. Thanks again for all your contributions though
I'm not familiar with a pipe spool, but I have done some tubes that I have modeled with solid sweeps and then shelled the wall thickness. You can then use mass props to get the "pre-shell" volume and subtract the "shelled" volume to get the internal volume.
How are you creating your pipe spool? Because you can always create the volume of the inside by not merging bodies together and then after you select the evaluate command clear the selection and select the internal body and recalculate to find the volume. Now, you can if you used a revolved boss/base command and defined the internal volume body and the external part of the pipe you can accomplish this in two features and one sketch. Like I said before just don't merge the bodies together and select a contour for the external revolve first then on the next revolve select the internal contour using the same sketch.
You could make a large bounding volume, use the mold cavity tool to subtract your piping, and then mass properties the remaining internal solid. This would basically create the internal solid for you.
That's the way I've done it in the past. It's a PITA, but it works.
model the core, then get the internal volume then shel outwards and then you get the part you want, or you can copy the body and shell the copy or original and have both.
Or you can use boolean operations inside the part. Read this:
Do you know the OD, ID & length?
why is OD needed?
LOL ... because I'm slowly going senile?
At least it's slow for you. Some of us aren't so lucky!
you have the id and the lenght? should be straighforward to compute using the equations editor. results are readily available in feeature tree.
Do you have empty and flooded weights?
