Need advice on specialist suction devices for "at Source" collection of small quantities of particles generated in a laser etching process. The process will only generate a couple of grams of particles per hour.
I am particularly curious about off-the-shelf duct inlets ,nozzles and...
Martin,
Have you got the spiral bound books that come with solidworks, there's a reference manual and then a smaller tutorial book. I did the tutorials and found them fairly explanatory. It mightn't be possible to buy them in bookshops so you may need to find someone in your area who uses it...
Have you tried any pipe flow programs? there is one available at this link

its fairly useful but i don't know for sure if it will solve your problem. You can insert a pipe element such as an orifice and it will calculate the flowrate across...
Thanks for the tip socrates. I think i'll use a flowmeter to get an idea of the total loss coefficient. I don't have any pressure measurement equipment handy.
Does anyone know how does one go about anticipating the pressure drop due to a complicated nozzle assembly stuck on the end of a vacuum extraction unit hose. the nozzle is annular (donut) in cross section and i can't find any equations for the entry/exit losses into an annular section.
All i...
