Quickie plumbing question

I sure am curious how the testing is going.

 

too much reading to be done.... who says you need all that knowledge when it comes to a glass box with some water in it?

Show off your degrees and your fancy knowledge... but what comes down to here is how good your plumbing is...

and so far I havent seen any plumbing.... or thoughts towards your plumbings since I read something about some engineer in training

 

It's wednesday already, still no test results?

 

let me get this out the way, I haven't been able to do the testing yet. Work has been keeping me busy. I did call the manufactor. I was told by them, (mind you Powerman this the people that made the pump) that there is going to be no drop in power consuption. However, after some time of use, as the motor wears down from working harder, there will be a decrease in power consuption. But there is also a decrease preformace, not as much flow. I will say that it doesn't hurt the life or the pump as much as I thought it would.Got my email back "The powar usage would be the same" Powerman don't believe me I will forword you the emails.

Powerman, your right I should not have assumed your education. Your attitude leaded me to believe you were a over righteous pre-pubescent button pushing girl. But you shouldn't assume that you can't be wrong, because you work with big pumps. As I know nothing of your acctual knowledge, you nothing of mine. This whole time it seems that you just want to show everyone that I am wrong. Well if thats the person you then fine. I am really done talking to you, because you are not worth my time. (by the way when you are talking about the varibles in that equation some are constants, your right but not everything in that equation is a constant. The only reason I mention my degree to hopefully show you that when it comes to math I know what I am talking, not to flaunt it).

To everyone else, I planning on still doing my testing this weekend, and I will publish my results soon. Its just a matter of getting the tools and the time to do it. I apologize this got out of hand, some people are just....

 

:

Humm... power consumption will not decrease... but as pump wears and there is a loss of flow there will be a loss of power consumption. Wierd

You come back and appologize.... by calling me names and basically say it's all my fault. But ya... I'm being immature. Nice.

I have been wrong many times... I can state with absolute certanty that I will be wrong again. Such is life. Helps me learn.

What my problem is is that you basically come in here and state to two people that have been doing this a lot longer than you that neither of us know what we are talking about. Perhaps you should take a look at your approach if you ever want to learn anything.

When I state 2+2=4 I'm not being an a$$... I'm just stating a fact. If you want to come up with some fancy math that says 2+2=10.... well I don't need to open my mind, and I don't need look at your "point of view"... I just need to point out your error. If you enjoy living in ignorance...carry on.

But enough from this little girl, I obviously don't have a clue. When you get your data.... please set AZDesertRat straight since all his data on power consumption and aquarium pumps for the last 35 years is all nonsense. I'm sure he will be greatfull.

 

I believe this thread to still be absolutely interesting. I'm really interested, specially in the test results. I looked at the equation and could not possibly understand that with my high school degree. But even though I'm foreign, I am fluent and most of the times, somewhat eloquent, but again, some of this math really escapes my brain because of lack of training. Regardless, my curiosity remains intact.

I appreciate it when the main participants in this thread dial back their words. You may feel like saying all kinds of stuff to each other, but for the sake of the "conversation" keeping thins civil it is definitely much better for you and the readers that are following.

I have no knowledge on pumps, fluid dynamics or advanced calculus and I am by no means arguing a single thing that has been said so far. I'm just curious about the outcome of this argument as far as whether it will save a tiny bit of power if I turn my silly valve down a bit.

To the mods: thanks for keeping this thread open. I believe we all see where this is going, but I still have faith in the maturity of their participants. I hope I'm not wrong on that.

I'm very intrigued!

Yes it will save a tiny bit of power.... but is it worth it to you...don't know.

The best example I can give is an Ehiem 1260/1262 pump.

Eheim Universal “Hobby†Submersible Water Pump

A 1260 flows 635 gph at 65 watts
A 1262 flows 900 gph at 80 watts.
(Same exact pump, more water flow, more power use... neat hu.)

The only difference between the two is the 1260 has a smaller inlet diameter. It is common knowledge that both pumps are the exact same pump, and you can turn a 1260 into a 1262 by ordering the bigger inlet from Ehiem.

So I crunched the numbers of using that 15w difference on a 24/7/365 basis using my cost for electricity....which is pretty cheap. The total for me came out to be $22 in power over the year. Is that a real big deal....not really. It could be as much as $40 a year is your power is exspensive.

Now over all in this hobby it is not that much money.... however, the point of it is you need to be aware of your energy use and have a strategy on how to reduce it and use it more efficiently.

So properly size your pumps, reduce flow where you can. If you need heaters to keep temp, then use internal pumps and use that waste heat instead of loosing it to the air. If you need a chiller to keep temps, then use external pumps so your chiller is not used to cool the pump waste heat. Use fans instead of a chiller (if possible). When you look at energy use as a whole there are usually savings to be had and more efficient ways to run what is really a luxury hobby.

 

doing a little looking my self and found this on reeflo's site

ReeFlo Pumps

 

Depending on the pump savings can be significant but it also reduces the flow due to the additional head.
Let me dig up some of the testing I did on an Eheim 1260, Ocean Runner 3500 and a few other pumps I had laying around at the time. It may not be this evening but I will find my old data and post it.
Power consumption is directly related to the amount of watre being pumped or the work being performed.

 

I believe that if I can save 40 to 50 bucks a year on any given year, I would definitely like the saving. It can go towards a set of new bulbs or new coral/s IMHO. Were the test results posted by suckafishtankcleaning ? I seem to have missed that post.
