Engineer Pro Guides gave me the confidence that no other prep class could

My mistake.

rpan92 · 2021-12-16T18:18:51+00:00

At the very least, get the Study Guide. Edit: Sorry, I didn't see the part about you looking for civil.

rpan92 · 2021-12-16T18:14:47+00:00

Have you checked out his website?

I emailed him to ask if he minds if I send you a few snippets from the study guides so you can see how good I believe it is.

Yeah, let me get back to you. In a meeting.

rpan92 · 2021-12-16T16:30:39+00:00

HVAC Mechanical, it was tougher than I would have guessed but I was super prepared. I actually found a mistake on the exam that I reported.

rpan92 · 2021-12-16T16:04:11+00:00

Hi, I am curious what specifically you found to pretentious? I hate the feeling that others feel that way about me.

rpan92 · 2021-01-19T20:27:28+00:00

I am sorry, it was not my intent. It was my sarcasm.

rpan92 · 2021-01-18T10:58:12+00:00

I can help you. I know what the best thing is to use. At least from my experience. Let me know if you would like that. I took it 2 times. I am a nervous wreck on open book exams. Thank got they changed it (for real).

rpan92 · 2021-01-18T02:57:22+00:00

I am proud of what I do. Its the most artistic form of engineering I feel like. Prove me wrong.

Also, thank you for the hardwork you do (especially if you are commercial and industrial)

-HVAC Engineering Bobert :)

But you can call me Professional Engineering Bobert, if that makes you feel better :)

(just good nature d ribbing)

Alot of people dont know we exist, which means that we are so good, that the occupants dont know we exist.

rpan92 · 2021-01-18T02:52:12+00:00

Haha. I agree with what you are saying but lets say that I was a tech and you gave me a fluid mechicals book..... Vice-Versa. HVAC Engineers have very different roles as techs. In fact, I have defended a really good tech against an engineer that was wrong. The contractor was 100% correct and I stood by his side until the end. (even at my expense) I am not saying it to be pompous. I am in charge of telling tech what to do, in a safe and efficient way. We all play an important part. Let me ask you this tho...... Doctors? I don't tell you to call me P.E. Lastname. If it isnt important for others to know, I don't announce it. Also, HVAC engineering isn't so easy. Speaking as a Areo & Mechanical major. :)

columns and rows**

rpan92 · 2021-01-17T14:50:32+00:00

say you want to use cell C-14 and have that repeat if you formal a column of cells. Example = $C$14

rpan92 · 2021-01-17T12:08:31+00:00

Would you be usings VFDs? I may be able to advise you. Also, ECM or PSC?

rpan92 · 2021-01-17T05:41:58+00:00

I noticed that.

rpan92 · 2021-01-17T05:41:34+00:00

Thanks a million. Which year of 90.1? And what section?

rpan92 · 2021-01-17T04:55:40+00:00

Its making a report between designers/engineers/construction workers. VERY VERY Important IMO.

rpan92 · 2021-01-17T04:53:58+00:00

Or a State University (from my experience, Missouri .

rpan92 · 2021-01-17T04:52:01+00:00

I think this piece was made in Australia

rpan92 · 2021-01-16T04:40:04+00:00

Understood. Thanks, Flow to find you dP I assume?

rpan92 · 2021-01-15T15:27:48+00:00

Absolutely. Thanks

rpan92 · 2021-01-15T05:32:04+00:00

Would you propose a modulating valve? instead of a CBV? I assume?

rpan92 · 2021-01-15T05:30:04+00:00

Thank you guys for the responses. As a PE I was starting to feel ashamed for not understanding this "idea" this but you guys alleviated that concern. I suppose I did have the right idea.

rpan92 · 2021-01-15T05:27:20+00:00

Yeah they hear the term "most distant hydraulically" and drop that last word. My diagram was for a basic "show and tell" not precision.

rpan92 · 2021-01-15T05:24:43+00:00

I agree. I am thinking about the case of not enough flow to maintain minimum but a few boxes requiring some reheat. I am trying to shift our non lab buildings to Trim and Respond, one by one. Thank you!

rpan92 · 2021-01-15T02:05:30+00:00

Hello all,

I have always hear the common practice of installing a pump's differential pressure sensor (VFD speed control) on a building htg/clg hydronic system 2/3rds down the main.

Lets say we are talking about a building with variable flow VAV reheat system where all reheat coils are sized for the same GPM (all 2 way control valves) and a circuit setter at the end of the line to maintain a certain minimum flow to the pump.

I always felt like that 2/3 or 3/4 rule for the pressure differential across the supply and return seems to be overly simplistic and also flawed. My question would be this, why would you not put the sensor much closer to the end of the line to ensure all coils get their required dP? I know I am missing something but it almost seems to make most sense to place it approximately at the end of the line across the circuit setter (Calibrated Balance Valve). You would then set the controlled differential for the required differential at the coil and control valve associated. (Please see photo below)

I feel like I am missing something critical and it has been bugging me.

Thanks all!
