Yesterday, we were testing a filtration unit with a fractional HP PSC motor. Oddly (to me) it is labeled 220V 60Hz. The rated RPM is 1050. So we ran this motor in our unit at the rated voltage using a variac. We were measuring RPM, current, and air flow through our filter as the motor is...
I am hoping someone more skilled than me can help me out. We are manufacturing steam manifold assemblies. The gray area that I am dealing with is TIME.
Each of these manifolds is completely unique and custom designed per job. Calculating the time for the shop routings (labor hours) seems...

I have read the Wiki(octane rating) on the subject already.
I have been having a discussion with a collegue about this and his understanding is that it is related to the flame speed... which I think...
I am looking for opinions on this situation. As a product development engineer, often times the success of the project depends greatly on how equipped the lab is. For example, if you don't have a multimeter... you probably would do much electrical work. Anyhow, to my scenario...

Does anyone know of a source for stainless steel finned tube? Approximately 1" ID... I am aware of wolverine tube, but it looks like they specialize in mostly copper. This is for a small boiler design that is being conceptualized. Thanks.
Does anyone know a source for this or equivalent material in China? or anywhere in Asia for that matter? Thanks for any information.
To be used in a condensing heat exchanger (natural gas combustion).
My company makes steam humidifers. One design is that of a tank with submerged steam pipes. I would like to get some help with my math please.
Assuming the tank is full and boiling (minimal back pressure) and steam is being fed at 5 psi, how can I calculate the amount of output steam I will...
