Remembering Ferran Guillén

The KYPipe family is heart-broken that we must announce the untimely passing of our beloved friend and colleague, Ferran Guillén, our KYPipe representative for Europe.  He was hiking in the mountains near his home when his heart failed.  He will be dearly missed by us all, both as a KYPipe teammate and as a true friend.  He was so enthusiastic, …

New Transient (Waterhammer) Modeling Book Released

KYPipe releases the new (2021) transient analysis book, Surge Analysis and the Wave Plan Method: A Powerful, Accurate and Stable Method for Water Hammer Studies, by Dr. Srinivasa Lingireddy and Dr. Don J. Wood. This book was written for both practicing engineers and academics. It compares and contrasts the powerful and stable Wave Plan Method (WPM) with the Method of Characteristics …

A Great Loss

Francisco Eduardo Veiga passed away from complications due to Covid-19, October 23, 2020. He was a great engineer and he had a genuine, heartfelt enthusiasm for hydraulic transient calculations. He did so much to encourage, share, train, and use knowledge in this field for the benefit of all of Brazil. But most importantly, he was a great friend. He brought …

Modeling Hydropneumatics Tanks in KYPipe

What is a Hydrotank Hydropneumatics tanks (hydrotanks) use compressed air to maintain the pressure in a distribution system as opposed to overhead storage tanks, which rely solely on water elevation. They are commonly smaller and less expensive than overhead storage tanks and are used to control pump cycles in raw water, potable water, and sewer systems. Modeling hydrotanks within a …

Revised Brazilian Standard Allows Wave Method

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 …
