Lol thanks guys for the tips and spirited discussion. It is a smaller scale application and not a true pipeline but hey I figure you guys would know best. Thanks again!

That’s a good point. I’ll probably install a little screw type Bleed Valve just for fun lol. Thanks

Dan1978 (Mechanical)(OP)27 Nov 17 02:54 Hello, I am installing an inline sediment filter on a domestic water piping system. We want to install a differential pressure gage mounted above the filter to determine when the filter needs to be changed. Incoming pressure would be about 50-60 PSI and...

Thanks LittleInch. The pressure differential shouldn’t be more than 10-15 PSI. With the incoming pressure at around 50-60 PSI. Am planning to keep the branch lines of equal length and short as possible. I figure as long as both lines are the same length and we’re measuring differential...

Hello Hope this is the right forum for this question. I am installing an inline sediment filter on a domestic water piping system. We want to install a differential pressure gage mounted above the filter to determine when the filter needs to be changed. The small 1/8” dia. pipes feeding the...

I would agree with what Abby said. Rules of thumb are only good if you have som eexperience to know when to not use them. See the post about heating and cooling loads software if you want an accurate load. Like Abby was saying, ventilation and people loading usually account for a good part of...

We use Wrightsuite Universal in our office. It uses the ACCA Manual "N", or the ASHRAE methods, Radiant Time Series and the traditional method. It has a graphical interface where you can load a floor plan and trace your different rooms or zones into the program directly. Its OK for medium sized...

Thanks for the information guys. If I had more time to design it I probally would have gone with one of the Exhausto systems as DrRTU suggested. This was for a church and local gas authority was threatening to shut off gas until a fix was installed.

When you say your measuring effectiveness, how are you determing that, and what measurments are you taking? Either way the condensation shouldn't be ignored, it takes quite a bit of energy to lower the temperature of water vapour enough so it condenses out as a liquid as compared to the same...

RossABQ/Compositepro; This was a first time for me using a Tjernlund product - they seem to be a big name in draft inducing fans from what I see. We did put an airgap as Compositepro mentioned. Created a draft induction hood above the termination of the existing flue exhaust vent. Just waiting...

Assuming you are talking about cooling air by passing it over a heat exchanger, the condensation represents a change of state of water vapor to liquid water. So in addition to any sensible temperature change you could quantify the amount of condensation and work it that way. Not sure of any...

Could send you a PDF but they are electronically secured when you download them. Heard about a guy who viewed them online took screen shots, cut and pasted into a viewing program and printed each page from there. Personally, I'd rather spend the $75 and get the real thing. It is available for...

RossABQ/Trashcanman; The manufacturer would not allow us to extend the vent any further. There is an existing vent extension kit installed there already. The unit is 250 mbh Lennox LGA and is mounted under an architectual feature that acts as an enclosure, so we have to get above the enclosure...

I have been reading other peoples threads on here for quite awhile so now I have one of my very own. The company I work for was involved in church project where some roof top units were installed. The local gas authority has an issue with the flue gas exhaust and wants it re-routed. All Lennox...

Hey Texanman, The air that gets drawn into the space your exhausting from adjacent area does not have to be 100% fresh air. As long as it is free of contaminents or is not itself polluted you can use it. ASHRAE 62.1 goes over the classifications of air within a building and what types of air you...

I think a good place to start would be to look at the manufacturers data on the equipment you are planning to use. Determine the latent cooling capacity of the equipment. Once you have that, look at the total volume of air in the building and determine per cubic foot how much moisture will be...
