It’s the Economy, Stupid. Or Is It?

A few months ago I attended a CEO forum in Colorado where a big topic on the minds of the 1000 CEOs in attendance was the state and direction of the US and global economy. The keynote speaker Brian Beaulieu began his presentation with this assessment of the economy from TIME magazine: The U.S. economy remains almost comatose. The current slump already ranks as the longest period of sustained weakness since the Great Depression. Once-in-a-lifetime dislocations will take years to work out.  Among them: the job drought, the debt hangover, the defense-industry contraction, the banking collapse, the real estate depression, the health-care...

The Quickest Way to Learn AFT Products

After you receive your AFT software , you will probably wonder how to learn the software quickly so you can begin using it.  AFT provides a very handy Quick Start Guide for each software product in English Units and SI Units.  These quick start guides are short, concise, would take maybe a day of your time, and are extremely powerful to assist you in producing highly accurate and advanced models! With larger companies, sometimes the AFT software will go straight to the IT department for installation and the engineer may never see the hard copy of the quick start guides.  Not...

Thankful for the Opportunity to Shape a Changing World

Wherever I go I see change. China is undergoing massive change in a relatively short period of time which has impacted Western nations both positively and negatively – as well as the rest of the world. China’s growth in manufacturing is impacting Australia in a huge way and driving much of the Australian economy through accessing its abundant natural resources. As we look back on the American Thanksgiving holiday I am currently on a lengthy visit to Australia and Asia training customers in the East and meeting new prospects. And seeing the changes first hand. My family is along with me and we celebrated...

How to Fill as Quadratic

Filters and screens impose a pressure drop that varies with flow rate. The variation is non-linear, but manufacturers will often provide only one data point for pressure loss at the design flow rate. Using a single point, or constant pressure drop, can produce significant inaccuracies in your model. With this in mind, AFT offers the “Fill As Quadratic” option for entering loss data.   Using only a single point, “Fill As Quadratic” will create two additional points for you. This first is simply 0,0; zero flow produces zero pressure drop. The second point is 2 x Flow and 4 x Pressure...

AFT Around the World

In early October, I conducted a 5-day training seminar in Lima, Peru. There were seven different companies represented from Peru and Chile. It is always interesting to see the variety of applications for AFT software and Peru was no exception where many of the engineers are involved in mining operations. Peru is a leading producer of copper, gold, silver, phosphate and potash with over $16 billion in exports in 2009. The engineers at the seminar had a variety of active project responsibilities. These ranged from long transport pipelines, to storage and transfer systems, to refining and process facilities. The course emphasized...

I have never heard of such a valve. Wish I could be of more help.

Where Did the Name "Fathom" Come From?

A frequently asked question at our training seminars - usually during a break or over lunch - is how we came up with the name "Fathom". More completely, the product is named AFT Fathom ™ and it is considered by many as the world's leading pipe flow modeling software product. The story behind the Fathom name is intimately tied to the story behind the founding of Applied Flow Technology as a company. So let's go back to 1993. AFT Fathom started as a hobby in 1992 while I was working in the power industry as a research engineer. But it was not...

Save Money, Reduce Energy and Improve Sustainability with AFT

The growing emphasis on sustainable business practices and environmental responsibility has impacted AFT software in several areas. In recent years we have added built-in capabilities to AFT Fathom and AFT Arrow to calculate energy usage and to estimate the cost to operate rotating equipment. This is available on the Analysis menu in the “Cost Settings” window. Using AFT Fathom, TME Energy Services Division developed a model of the chilled water system at the University of Arkansas . The project realized an annual energy savings of 1.9 million KWHr and $67,000 in pumping power and $1,200,000 in annual chiller electrical and gas...
