Modeling Free Flow from a Tank in PIPE-FLO (Speed of Efflux)
The velocity of fluid when draining a tank is frequently referred to as Speed of Efflux. When modeling free flow from the bottom of a tank in PIPE-FLO, an accurate representation of the resistances must be made in order to get accurate calculations. If a tank has a discharge port running directly out of the bottom, then the PIPE-FLO model must be represented as the image seen here (Speed of Efflux.gif). In PIPE-FLO a small pipe, resulting in nearly zero resistance, is run from the bottom of a tank to a free spray (0 psig boundary pressure). In order to accurately model the resistances leaving the tank, an exit fitting, which will represent the exit losses from the tank into the pipeline, must be included in the pipe. If the exit fitting is left out of the calculation, it will prove detrimental to the velocity calculations in this type of scenario. (article cont. here)
This article will discuss PIPE-FLO's method of calculation of the fluid velocity out of a tank with a discharge port at the bottom and how to appropriately model this scenario. It also covers why, when modeled correctly, PIPE-FLO calculates the equivalent velocity as Torricelli's Theorem.

Your PIPE-FLO® and Flow of Fluids Software Training
There is still a little room in our Cincinnati, Ohio class scheduled for
May 8 & 9 but time is running out, so reserve your seat today. Save your spot today in our
final FLO-Master for Spring 2008, call 800-786-8545 or email
sales@eng-software.com.
Classes resume in the Fall so check out our
list of Fall dates on our website.
FLO-Master seminars are two days, lunch included, with the second day completely
focused on real-world examples and hands-on use of the PIPE-FLO program. All the newest features are covered as well as the program basics for anyone who needs a brush-up on the essentials.
Examples will include advanced pumps and controls, variable frequency drives, two-way communication with Microsoft Excel using X-Link, balancing a system expansion, sizing pumps in series with a large campus chilled water system, and dynamic time simulations with Overtime.
Spring 2008 FLO-MASTER Schedule:
Cincinnati, OH ● May 8-9
Fall 2008 FLO-MASTER Schedule:
Philadelphia, PA ● Sept 18-19
New Orleans, LA ● Oct 16-17
Las Vegas, NV ● Nov 13-14
If you find that these dates and locations will not work for you, we also provide onsite training opportunities. For more information about onsite training or the course outline for our FLO-Master seminars, visit our website at
http://www.eng-software.com/products/flomaster.aspx or call (800) 786-8545.
All FLO-Master seminars qualify for 15 Professional Development Hours needed to fulfill Professional Engineers’ continuing education requirements in many states.

Spring Training SOLD OUT!
Our new Piping System Fundamentals training class was a total hit! Classes were so popular we are sold out for the Spring but we do offer
onsite visits for those of you who are interested in hosting a class. We are planning for our Fall training schedule and are open to suggestions for future locations. If you have a suggestion please email
marketing@eng-software.com.
The two-day, Piping System Fundamentals course has been developed for anyone needing to obtain a clear picture of the operation of the total fluid piping systems. This course does not explain or include tutorials on particular software, but instead discusses meaningful principles that explain why and
how piping systems physically work and operate.
Piping System Fundamentals courses use a minimum of math formulas with an emphasis on understanding the relationships between components making up a piping system. Attendees will receive a course workbook, a copy of CRANE’s TP410, and the new book
Piping System Fundamentals: The Complete Guide to Gaining a Clear Picture of Your Piping System. The course is worth 1.5 Continuing Educational Units (CEU) or 15 Professional Development Hours.
