Preventing Climate and Other Disasters
Controlling the Future - Controlling Nonindustrial Processes: Preventing Climate and Other Disasters. Many books have been published about stopping global warming. What sets this book apart is that it applies the science of process control to analyze the warming process. To control a process, we must fully understand it. Global warming is analyzed here as a heat balance process in which Earth is warmed by the Sun and cooled by outer space. For a million years these heat flows were in balance...

Prevent the damaging effects of pulsation
in piping result from the pressure spikes created by the pulsating flow. Remedy. Suggest that you install a pulsation dampener. Dampeners provide the most cost efficient and effective choice to prevent the damaging effects of pulsation. A surge suppressor is in design essentially the same as pulsation dampener. The difference primarily lies in sizing and pressurizing. Conclusion. By knowing how to avoid situations that will create water hammer or pulsations during the specification process...
