nbucska, We don't have a web site yet. That is another thing I am supposed to be working on. wlowery@ddplumbing.com

You can achieve want you want or at least something similar. Here is what I have done in the past. I used Wonderware and Excel to create a power plant monitoring system. I used Wonderware just as a GUI. I performed all calculations in one Excel Workbook, stored them all in another Excel...

I am looking for literature (preferably OnLine info) about Geothermal Injection wells, artesian wells, and aquifers. Any suggestions?

A Commercial Iron Working Building....not too large....approximately 7500 square feet..

I am looking for typical sizing criteria for Sand and Oil Interceptors. I know that the Interceptor Size is typically calculated using the following formula: Retention Time * Waste Flow Rate = Interceptor Size But what are typical values for Retention Time and Waste Flow Rates for various...

The R-Value of granite that thick will be somewhere around 4.5. That is fairly high, so you may want to increase your tubing size and also space your tubing fairly close together. And of course don't forget to put insulation underneath the tubing to prevent downward losses. You also may have...

Does anyone know of any Books or On-Line Articles about Parallel Piping systems and how to calculate the system head loss? Also does anyone have any recommendations for software programs that work well for closed loop parallel piping systems (HVAC two and four pipe systems)?

I think you are looking in the wrong place....ASHRAE deals with heating and air conditioning. Nonetheless, I used to work for a power company, and we used the GE manuals and the correction curves in the manuals to determine what the heat rate should be at our ambient conditions. Good luck.

Nice add in thanks for the link, too bad it only does SI units.

poetix99, Hey I think you got the wrong thread. The one you put in doesn't say anything about an excel add in. I would like to find a free add in. Please try to find the thread and post it here again. Thanks. Way

Roberto, We reviewed Optimax, EtaPro, and Westinghouse smart process; and finally decided to go with EtaPro by General Physics. The EtaPro system had a lot more to offer including: using PI historian, incorporating additional tools to work with PI, first class calculations, ease of use over...

I have been having a hard time setting up Layouts to scale correctly to the scale I want (usually 1/4"=1'). I also cannot get my linetypes to transfer from my model(drawing space) to my layout and plot. Any suggestions on these areas is greatly appreciated.

I am fairly new to the HVAC world, and I am trying to get up to speed on designing heating/cooling systems (especially forced air). Can anyone recommend any good books or short week long classes that will get me headed in the right direction? Thanks.

I am trying to draw piping Domestic Waist and Vent isometrics, and I am not doing so well. I usually switch to the SE viewpoint and go from there. I have troubles when I change directions, and start trying to draw fittings. Any Suggestions?

I am designing a combustion air system for a residential home. The Mechanical room has appliances that total 573,000 btu/hr. The General Contractor has suggested that we place two openings (12"x12")in the mechanical room wall that will feed into a small storage room that will have...

Shmulik, Is the arsenic dangerous? I don't know what you mean, but I'm sure that if you ate enough arsenical admiralty tubes that you'd get pretty sick. However, I don't think there is any risk handling the tubes. We have arsenical admiralty tubes in one of our condensers, and we have been...

At several of our power plants, we burn #6 Fuel Oil and Natural Gas. I have seen our Heat Rate improve by 4% when we are burning #6 Fuel Oil. Unfortunately, I have no idea why. That is about all of my experience on the issue. Way

MGM, I took and passed the PE exam last year. I purchased the MERM study package, and I found it to be a great reference and great study tool. I also purchased sample questions from the NCEES. I focused on several areas with a combined total of 12 questions (about the same as bradh). I...
