How to Use the Flow Control Device in PIPE-FLO® v15

Two new devices have been added to PIPE-FLO® Professional version 15 to perform a thermal analysis of heat exchangers used in a wide variety of applications throughout various industries. The heat source/sink device and the heat exchanger 2-pipe device are used to evaluate sensible heat transfer into, out of or between flowing fluids. One of the optional design data fields for these two devices is the flow control device (FCD). Assigning an FCD establishes a process control link to another device in the piping system model to regulate the flow rate through the heat transfer device. It, therefore, controls the heat transfer rate, inlet temperature or outlet temperature as well.

Maximizing Pump Modeling with All-New Pump Operating Modes

PIPE-FLO® Professional Version 15 incorporates several improvements to existing features as well as all-new heat transfer functionality, 15 new calculations and enhanced reporting and automatic solutions for several over-controlled scenarios. One of the new features in PIPE-FLO® Professional v15 is the addition of three new operating modes for the centrifugal pump and sizing pump devices. The new discharge pressure, suction pressure and temperature control operating modes provide more flexibility for the user to model real-world process controls and evaluate system performance in PIPE-FLO®.

Over-Controlled Improvements Coming Soon In PIPE-FLO® Professional v15

The over-controlled message in PIPE-FLO® has historically been difficult for users to understand and reconcile. Improvements being made in PIPE-FLO® Professional v15 will address the conditions that cause an over-controlled message. An over-controlled condition is created when a user designs a piping system, and a portion of the system is isolated from a pressure source, resulting in an infinite number of solutions that could satisfy the Conservation of Energy.

Maximizing System Efficiency Using Manufacturer Supplied Pump Curves

A critical step in maximizing the efficiency of a piping system is properly sizing and selecting a pump that best suits the operation. With PIPE-FLO® users have access to over 120 pump manufacturer digitized pump curve catalogs. Having access to a manufacturer’s supplied pump curve is highly beneficial since all manufacturers’ electronic pump curves have been created, reviewed, and approved by the pump manufacturer. This month, we will explore how to enter pump data from an electronic catalog.

Evaluating the Parts: Building an Energy Cost Balance Sheet for Each Item

In our previous series of articles, the ESI News Brief thoroughly discussed on the benefits, development, and analysis of an Energy Cost Balance Sheet for an entire piping system. In that series, we also covered how to calculate the cost of operation for a centrifugal pump using the manufacturer’s pump curve. Our next series picks up where the last one left off. This month we will see how to perform the detailed cost calculation for the other items in the system.

Understanding the Over-controlled Message in PIPE-FLO® Professional

There are several common reasons why a piping system can throw an over-controlled message in PIPE-FLO®. Due to the way PIPE-FLO® “sees” each device, the over-controlled condition occurs when a portion of the system is isolated from a pressure source, resulting in an infinite number of solutions that could satisfy the Conservation of Energy, thus PIPE-FLO® cannot arrive at a single solution. Read this month’s article to learn how to avoid over-controlled scenarios.

Efficiently Planning Data Center System Expansions with PIPE-FLO®

Data Center expansion is a multi-variate undertaking that can lead to unforeseen constraints and unnecessary expenditure if underlying assumptions are not confronted. Determining how and whether the expansion will fit within all elements of the existing infrastructure takes careful analysis that can require long, iterative processes to resolve. Using PIPE-FLO® engineers can simulate proposed changes, discover potential issues and avert costly mistakes.

Ensuring System Accuracy by Utilizing Customized Pipe Tables in PIPE-FLO®

The pharmaceutical industry in the United States is rapidly expanding in order to accommodate the need for new pharmaceutical products. Due to FDA guidelines, the production facilities making these new products must be designed, built, and commissioned to meet stringent criteria. To ensure these complex systems are built correctly it is critical to be able to accurately simulate conditions using hydraulic network analysis software.

What is a Siphon and How Do You Account for One When Designing a Piping System?

A siphon is a natural phenomenon that can occur in any piping system that transports a liquid from a higher elevation to a lower elevation. When designing a piping system for any industrial or commercial facility, it is important to understand how and where a siphon may occur, and whether the siphon will be working for you or against you during system operation. Failure to take the siphon effect into account can lead to collapsed tanks and pipelines, downtime, lost production, safety hazards, and environmental excursions.
