How do I calculate the noise generated when air is expelled from a 1" pipe open to the atmosphere. Air is at 132 degrees F at a pressure of 2 psig inlet and 0 psig at the outlet, and ambient temperature. Velocity is 35 ft/sec.
This comes about when a tank is under 2 psig pressure, and is...
The jacketed vessels being utilized are not coded vessels...they were purchased used from who only knows where. Prior to their being placed in service (and this has not happened as of this writing)the jackets were filled with water and 10 psi air pressure was applied. The gage held for over an...
With all things I have done as an engineer, I have never sized a psv.
This psv is on the discharge of a 2x1 centrifugal pump that circulates hot water in a closed system to provide heat to a couple of jacketed vessels then back to and through a small hydronic boiler. Temp of product is 45...
An expression I use frequently is "they don't know they don't know"...so how can they know what questions to pose? I too am in this category on some things (spouse will say "many"), but I have to purchase a temperature element that will be used with a PLC to determine when to open/close valves...

My co. charges their tumblers with 40mm size styrofoam balls, coats them (spray)with an epoxy and then some sort of fiber...all designed to increase the density to a specified point. What would be considered a "best" design for the subject baffles to assure a thorough coating of epoxy and...
