I have a question concerning pressure changes. We are trying to make small pressure changes to a static pressure of 5psi by varying the volume in a cylinder.

Question about settings for our thermal relief PRVs around valves in tank farms. Nornmally we have the PRvs set at 25 psi in the piping and 75 psi at the valve directly off the tank (our tanks are not

My company builds industrial sized centrifugal fans (40"-120"+ impeller diameters), and we treat "Fan Engineering" like it is the Bible.

No power since 8am now 3:30pm PoCo thinks they'll have it back on by tomorrow at 3pm. So it's on to the generator for keeping the business running. Never mind we're in the middle of a town of 50k an

Is there an industry standard or performance expectation for 2 wire 4-20mA output devices (actuators, positioners) for signal levels below 4mA? For example, many field transmitters incorporate special

Would like to get a definition for hysterisis. Looking it up gives 2 definition. 1. lagging behind of flow upon movement of valve 2. difference in measurement for the same amount of flow measured

In rebuilding a Mercury Sportjet with Force 90hp stroke I used Wiesco forged pistons but they do not have the 2 large diameter (approx 1") holes on the pistons intake skirt as the originals had. Wiesc

We've been having issues measuring small flows in a high temperature high pressure application. We're talking 5 pounds/hour of product.
