    Help Building Simple Pipe Bend (Experiment)

    Take a step back. First, what is the objective of this? It sounds like you are just setting up a pump to recirculate water. Second, what pump rate do you want for this. 500 gpm is a lot and takes a lot of horse power. Set your flow rate to a little above what you need for the experiment to...

    Natural frequency causes harmonics. In machinery this is bad because it creates high loads at the cycle peak usually far higher than desired. For pumps, it can cause the bearings and the seals to fail early, damage the drive motor, etc. I have seen harmonic vibrations tear piping systems to...

    Optimizing Chemical Injection for Viscous Polymer in Winter Conditions

    Your system is designed to function at a minimum temperature which is why you have problems during the winter. You need to determine the best temp range for service and install heat tracing and insulation. If the range is tight, you need to use an active controlled heat tape. If it is not...
