It’s a Pump Properties Party!

Everyone loves to celebrate. Here at AFT, we are celebrating the release of AFT Fathom 10 . One of the great things about AFT Fathom 10 is that the new and improved Pump Properties window makes specifying pumps faster and easier than ever.  This blog will provide an overview of the features that have been added or changed within the Pump Prope...

Determine Your Pumps BEP and Know API-610's Recommendations

What is BEP & why is it important? Every pump has an ideal range of operation where the pump is most efficient. The peak of the efficiency curve is known as the  best efficiency point (BEP).  Determining how far your pump is operating from its BEP is critical to increasing pump reliability and efficiency as well as meeting  API 610 recommendations .  AFT Fathom  models pump curves with efficiency data and will determine the margin between the simulated operation of the pump and the actual best efficiency point. Our friends at Empowering Pumps shared an article  titled, " Some Effects of...

Calculating Pressure Drop Across Sharp-Edged Perforated Plates

Sometimes design engineers will install a screen to protect equipment like centrifugal pumps. Screens are available in a variety of configurations and each has its own head loss characteristics. As such, this article will strictly discuss thin-walled perforated plates with uniform diameter holes. AFT Fathom provides a screen junction that allows users to choose from four different screen types; Perforated Plate (Sharp-Edged), Perforated Plate (Round-Edged), Circular Wire, and Silk Thread Screen. Every screen has an open flow area that allows the working fluid to bypass the screen while restricting any foreign objects that are not able to pass through this area....

NPSH got you under pressure? This’ll get you pumped!

Cavitation is an important subject in piping systems. Quite often, cavitation is an operating condition that is to be avoided, such is the case with pumps. Not only can cavitation cause serious decreases in pump performance, but it is also a maintenance nightmare if left unaddressed. Such issues are costly and may lead a system to be deemed unsafe. As you are likely aware, cavitation exists when the local pressure falls below the vapor pressure of operating fluid. Overtime the pressure may increase again so that the cavity formed then collapses. When this collapse occurs on the vanes of a centrifugal...

Integrating Component and Fitting Losses into a Single Pipe on the Workspace

Many components, such as isolation valves, elbows, and adjacent area changes, do not need to be modeled graphically when a simple k factor will suffice. In these cases, the AFT Fathom user can simplify and avoid unnecessary workspace clutter by integrating this data into a single pipe specification, using the Fittings & Losses tab. Fathom has a built library of component loss data provided by Miller, Crane, and Idelchik. The Fathom user can quickly and easily pick from a database of components, enter the quantity, and click OK. It is important to note, however, that Fathom uses the size of the...
