Effective August 17, 2017, Brazil has revised Standard ABNT NBR 12215-1, Project Guidelines for Water Mains – Part 1. Pressure Lines. The previous standard only recommended transient calculations using the Method of Characteristics. The current revision allows for the use KYPipe’s Wave Plan Method (or Wave Method). The revisions to the standard also recommend that the software be validated, that …
Non-Reopening Check Valves
What is a non-reopening check valve? This element is a modeling convention, as opposed to an item that can be ordered from a manufacturer, because by definition a check valve is designed to open and close in response to flow and pressure conditions. The way Pipe2016 models an “ordinary” check valve is by allowing it to open when the differential …
