Hi guys, I'm a junior engineer designing a kind of industrial shower head nozzle for water. I wonder how to calculate optimal nozzle dimensions given pressure drop/flow rate. I'd like to make or find an excel spreadsheet to do this. DO I simply calculate as if I'm designing a single orifice...

Thanks Jari, The fluid velocity I'm estimating is around: 13.3 m/s (44 f/s) Looking for somebody that will be able to help with this.

It's a bit a of a unique design- different in design to typical fluid bed reactors. It will be fluid moving through a relatively densely packed bed. The nozzle will not be doing any filtering, it will just have an in-built perforation to contain the catalyst beads INSIDE the vessel. There...

Hi Engineering gurus, I am tasked with designing a nozzle for a kind of fluidized bed reactor, which will have high temp oil flowing through it and a catalyst of around 1.5mm diameter. The vessel will be a cylinder of 40cm d. x 250cm l. Problem is, it needs to be back-flushed so must have some...

Hi gang, Any suggestions on how to put this darn WC nozzle into a custom flange so it will not budge and may be removed down the line for replacement? I'm sort of out of my league here; I need to figure out a way to secure a tungsten carbide flow jet (effectively a nozzle or plug) into a steel...

Cool, thanks for the input guys- I am stoked to have your brain time.

This is for a high voltage product

Does china have a UL code equivalent?

edit: ptfe is out due to cold flow problems.

Howdy all, I'm working on a high voltage insulating, high temperature ~300c prototype device. PEEK is currently being used as an insulator in the device, does a higher temp resilient insulating material exist besides ceramic? Thanks all! Cameron

Howdy all, I trying to proof test a prototype pipe flange cap that will be mounted to a 300 series 3" vessel that is designed to a limit of 25 bar and 250c. The pressure is a no-brainer, but I wonder if there is a way to safely test the temp concurrently. I am in communication with my local...
