Slug force calculation in piping
WebbWater Hammer Calculation An abrupt change in the velocity of a flowing liquid in a pipe generates a pressure wave, which is commonly referred as "Water Hammer". This tool was developed using the Joukowsky equation to provide you with a simplified method for calculating the peak transient pressure experienced when a valve is closed against a … WebbPiping/Pipeline systems can be protected against Surge impact by using devices during pipeline normal operation like: Variable speed pumping: Variable speed drives provide a …
