Pipe slope is a critical element in reducing water collection following a sprinkler system drain. Water removal is important in that the largest detriment to sprinkler system life, corrosion, occurs across interfaces between air and water. Here is a quick summary of the minimum pipe slope requirements for fire sprinkler systems.
Components of a Return Bend
A return bend is the piping arrangement for pendent sprinklers where piping stems from the top of the branch pipe (riser nipple), runs horizontally (arm over), and then down to the sprinkler (drop).
Where Required
Raw Water Sources, Mill Ponds, Open-Top Reservoirs
Where Not Required Deluge Systems

Early in my career I realized that the value an engineer has is in the knowledge he or she gains and can then convey in order to help others.
Traditional thinking is that experience is the only way to gain knowledge and build value. While that may be true in large part, those who wish to learn without compromise naturally have more to gain and more to offer others. In this blog I hope to note takeaways I've gathered and topics which I hope to explore in more detail as part of my effort to be a relentless learner. It is my way of cementing details I've explored while garnering feedback and learning from knowledge of others. If you have not already subscribed, you can do so by visiting the Blog and simply entering your email on the right hand side. Thanks for being a part of the journey. When I was prepping for the P.E. Exam, I did what most of us do - ask anyone and everyone within about five cubicles who had recently taken the exam and what they did to pass. After taking the exam, I crafted a few ideas of my own and later even surveyed our users about their tips. While there's a variety in the responses, this is the best of what we found: 1. Organization
As the last post alluded, there's now over 6,000 pages of reference material ranging a handful of different topics spread out over seven references in ten volumes. That is a ton of information. Do I actually need to read everything? No, definitely not. Not only is it difficult to digest every page, but study time can be much more effective elsewhere. What is important is to organize the information for yourself so that you understand where to find critical information quickly. This has been done by creating a flow diagram which organizes references by topic, by using a formula sheet as your organizing tool, or it can be as simple as studying the table of contents from each reference. The end goal with organization is that you feel comfortable knowing where material is located so that you can quickly get to it on the exam. Congratulations, you have bragging rights over those pesky mechanicals. NCEES recently published the latest P.E. Exam pass rates across each exam discipline, and fire protection tied for 3rd out of 24 disciplines for the lowest pass rate for first-time exam takers and 6th lowest overall. The passing rate of 61% for first-time fire protection trailed only software (56%) and nuclear (58%) engineering disciplines. Overall passing rates rank fire protection 6th most difficult, trailing nuclear (42%), software (47%), environmental (49%), civil - geotechnical (49%), and civil - construction (49%). These numbers include repeat takers.
In preparing for the Fire Protection P.E. Exam, I felt a overwhelmed. There were over 6,000 pages of material to review and an array of calculations I needed to understand on topics which I didn't have experience. I struggled initially even to find what review material existed, much less to find quality review materials to prepare for the exam.
All I really wanted was to know what helpful material existed and what was critical for the exam. For three months I delayed even doing practice problems and instead scoured all of the required references to create a comprehensive cheatsheet that I could use as a table of contents/quick reference/formula sheet to save time on the exam itself (this later became the beginnings of the PE Prep Guide). After taking the exam, I quickly realized that our fire protection niche has left many others with that same feeling of having to blaze their own trail to study for the exam. MeyerFire.com was built to combat that struggle by (1) identifying what helpful material exists, (2) building a community for collaboration, and (3) to save you very precious time in preparing and taking the exam. This site exits specifically to help you. Looking to post questions or collaborate with others studying for the Fire Protection P.E. Exam?

We are excited to announce that the 2016 MeyerFire PE Prep Guide has launched! ![]() Content The 2016 Prep Guide This Prep Guide is specifically designed to help you pass the 2016 Fire Protection Principles of Engineering (PE) Exam. It contains: + Over 150 of the most important formulas for the exam + Specific page references to 2016 referenced materials for variables, formulas, and example problems + Symbols list and unit conversion table + A full-length, 80 question, peer-reviewed sample PE exam with thoroughly worked solutions This guide does not contain introductory and overview learning material which is already available within the required reference materials. Instead, this prep guide provides the most critical formulas and practice to help you efficiently prepare for the exam and quickly capture solutions on the exam itself. Feedback Received We sent a survey to every customer of ours from 2015: 80% of respondents said they used the formula sheet on at least half of actual exam problems and every respondent (100%) said they would recommend the MeyerFire Formula Sheet to a friend. Here's what they said: "More complete and better organized than other formula sheets available online." "Saves you time." As compared to other formula sheets: "Much more thorough, more helpful." "Much more extensive explanation of the variables." "Very well laid out." "Great explanation of the variables." "Helps on the exam and while studying." "Using this sheet as a starting point, I spent a lot less time cobbling together these formulas and cross references and in turn spent more time studying and getting comfortable with my reference material." Launch Special You can find the Prep Guide either on Amazon, and our Online Store. The best price available is only at www.meyerfire.com. |
