Where to Start with Pump Startups

Any time a rapid transient occurs in a piping system, there is a chance for unexpected surge to impact the system. Though system shutdowns account for many surge events, pump startups can cause water hammer as well. For this blog I am going to cover the basics of setting up pump and valve transients for the startup case in AFT Impulse 7, as well as...

Size Up Your Options Using the ANS module

When working on a new piping system, there are many factors that must be taken into account: meeting customer demands, following industry standards, and maintaining effective system operation to name just a few. As a busy engineer, it is important to address all of these concerns in the short time frame available to you. AFT's new Automated Network...

Applying the Improved ATKF Method for Laminar and Non-Newtonian Flow

If you have worked with Non-Newtonian fluids or low velocity systems in AFT Fathom or AFT Impulse before, then it is likely that you have worked with the Adjusted Turbulent K Factor (ATKF) method before. The ATKF method can be used to adjust K factor data developed for turbulent flow conditions to better predict loss in the laminar f...

Raise the bar using Vacuum Breaker Valves

Vacuum breaker and air valves are useful tools in the industry for protecting pipelines against vacuum or near vacuum conditions. High points in the pipe can be susceptible to these low-pressure conditions during surge events, as pressure waves moving through the system cause a sudden pressure upsurge or downsurge. AFT Impulse can help engineers to...

Meet the Import Piping Layout Wizard

When completing the analysis on a model, there is nothing more frustrating than having to do the same thing over and over again. Thankfully, using AFT's Piping Layout Wizard you will no longer need to rebuild your CAD, CAESAR II, and EPANET files to analyze the hydraulics using AFT Fathom, AFT Arrow, and AFT Impulse. In addition to GIS sh...
