Surge Analysis – Accurate and Efficient
We really enjoy developing features and working with our many users of our transient flow (waterhammer) software. Take a look at the new animated profile display coming with Pipe2010: Surge. This tool...
View ArticleMeters – a very useful unique Pipe2000 modeling feature
One of the most daunting tasks associated with modeling water utilities is handling the demand distribution for the water utility. It is necessary to develop a baseline model where an average demand...
View ArticleAutomatic Residential Demand Distribution – A Great New Feature
The use of meters to handle demands for water utilities was discussed in my last blog. The recommended approach is to use our meter connection element to represent the large users. Residential...
View ArticleLet’s Protect our Drinking Water Systems from Low Pressure Transients!
A few years ago I worked with American Water (the USA company with the largest number of water utilities) on an AWWARF project on pathogen intrusion due to low pressure transients in drinking water...
