Can anyone give me an effective but simple way to clean/flush schedule 40 steel steam piping and schedule 80 steam condensate piping used in a small process steam application (100 psi, 2" pipe and smaller).
I've seen references to open steam blowing and fresh water rinses, or simply wasting...
I am involved in the planning of a new chiller plant where the Owner is interested in using waste heat (steam) to feed absorption type chillers in the summer. We are in the far north where our season is short (long periods of chiller downtime) and chillers are usually not required at night...
Does anyone have access to an old Baltimaore Air Coil (BAC) selection guide (book) for a VS series cooling tower? I'm trying to recommission a 1974 vintage VST cooling tower and have been unable to track down performance data for it. The factory (so I've been told) scanned their old catalogs...
Hello, I'm getting involved in the design of a chilled water plant (approximately 3000 tons)for HVAC cooling. Our location has a load profile with ALOT of cool temperatures 55F to 64F), so part load performance (of the total calcualated plant load) will be important. Because the chiller plant...
Can anyone give me a quick summary of their experience with BTU meters? Is a turbine flow meter better than electromagnetic or vice versa? Which is more reliable? Which is more accurate?
My application will be heating loops only with propylene or ethylene glycol.
Thanks.
Does anyone know of a Consultant or Firm that has expertise in calculating heat transfer and/or temperature profiles of a complex "fin"? Specifically, this application involves steel beams that penetrate a building's insulation envelope and are welded to structural steel. Preferably someone...

About a year or so ago, I read (and didn't finish) a good article of the relative merrits of return vs relief fans in HVAC systems. I now wish to read the article again but can't remember which magazine I read it in (I've since moved and had to clean out my magaizine collection. Does anyone...
Can anyone tell me where I would find the definition of "medium pressure" ducting? I've looked in my SMACNA manuals and can't find it. Is this, perhaps, an outdated definition. Everyone uses the term, but I can't find a definition written down anywhere.
Does anyone out there know how fast I would have to run air out a vertical open ended duct in order to overcome an average rain fall (and not rain into the duct). What are your sources or where should I look? Thanks.
I'm designing HVAC systems with humidity control for a museum and wish to know if someone can tell me or lead me to information on the short term effects of a passing thunderstorm. Project is in Fairbanks, Alaska where where summer temps and rainstorms could dramatically raise humidity levels...
Has anyone come up with a good way to tie an infiltration calculation (such as the ASHRAE "crack method") to the requirements for make up air due to a building's exhaust system? UBC gives an exception for combustion air if the room is large enough, but I've never been able to dream up...
