How to Validate Data Going In To Python Script

The true power and flexibility of the Data Import feature in PIPE-FLO® Professional comes to light when taking advantage of Python™ scripting to generate or retrieve data. However, locating and correcting bad data in the .csv file being read can be a challenge. Fortunately, Python™ provides some avenues to catch these issues in advance and help users make corrections in an expedient manner. Below is information about a Data Import script that is robust, accurate, and time-saving across multiple files and users.

Minimizing Choked Flow with PIPE-FLO®

When designing and installing a piping system for liquid service applications, the location and type of valve selected for process control plays a major role in whether the valve will operate smoothly or experience cavitation or choked flow. These severe operating conditions not only damage the valve and increase maintenance costs, they could also create safety hazards to plant personnel. Using PIPE-FLO® Pro to model the piping system, a problem such as choked flow can easily be identified and solutions evaluated in the model prior to implementation.

A Financial Justification for Pumped System Improvements

In a typical industrial plant, 20-50% of the power consumed is for pumping applications. Pumped systems generally have an average system efficiency of less than 45%. This article shows how using readily available plant production data a pumped system improvement program once implemented, will increase plant profitability while reducing plant maintenance and operating costs.

What is the Difference between the Effectiveness-NTU and LMTD Methods for Analyzing Heat Exchangers?

As with any engineering problem, there are various ways to approach a solution when sizing and selecting a heat exchanger or analyzing its thermal performance. If the selected heat exchanger is undersized, the design heat transfer conditions will not be achieved. The Effectiveness-NTU and LMTD are two solution methods that approach heat exchanger analysis from different angles. Understanding the difference between these two methods starts with knowing the key terminology and equations used in each.

How to Avoid Over-Controlled Errors by Correctly Modeling Pumps in Series Using PIPE-FLO®

Pumps are often operated in series when pipeline and component losses in the system are substantial, and it is not feasible to achieve the required total head with a single pump. Series pump operation is easily modeled in PIPE-FLO®. It’s easy to set-up the sizing of pumps for series operation with a few additional steps. Read this month’s Take a Deeper Look to learn more…

Knowing Your Zero Can Reduce Costly Mistakes

In life, numbers are used to describe the amount of something, whether it’s the cost of a product, how fast you are driving, or how old your children are. But a number is meaningless unless it has two things: a unit and a zero reference datum. In engineering, miscommunication, confusion, and costly mistakes occur when numbers are used without proper attention to units or their relationship to a reference point.
