Hello,
I am trying to determine how to use the standard psych chart in calculating the sensible and latent loads for a space. It is located in Salt Lake City, UT and will be a once through system.
I know that there will be a factor applied for the difference in air density ratios. If so I am...
I was wondering what the mechanical property effects, if any, there would be in using an oxyacetylene torch to cut rusted bolts from a structural member. The structural member is made from ASTM A 572 Grade 50. The bolts are ASTM A 490 Type 3, nuts ASTM A 563 DH3 and washers ASTM F 436...
I am new to HVAC design and am looking for a little a guidance. I need to determine the cooling load for a unit that will supply a room with 100% outside air and 0% return air. The room will be exhausted at a rate of 6 ACH. This gives me a minimum air flow rate through the unit. I understand...
Hello,
I am trying to calculate the joint integrity for a flanged connection at 1200 deg F per ASME BPVC Section VIII, Division II, Appendix 3, Article 3-1 . I need the allowable stress values for ASTM A-193/ASME SA-193 Grade 8M fasteners up to this temperature. I have looked in the ASME BPVC...
Hello,
I am trying to determine if the Mannings's Equation in a gravity flow system takes into account various losses due to fittings (i.e., elbows, tees, diffusser header, etc.).
If not, would the applicable formula be the Hazen-Williams formula that takes into account these losses fittings...
I am looking for a good general use book on welding. I do not do alot of specifications for welding, but when I do I need a good reference book for symbols, material compatability, types of filler material, etc. Can anyone provide some good "desktop" references?
Thanks, aumechengr
What type of copper tubing should be used for air lines? Line pressure will be limited to a maximum of 125 psi. I have seen some information on B88 Type L copper tubing but am curious if there is another option. One thing is that the connections have to be done with compression fittings so an...
I am currently working on a project where I have to run a CO2 line underground. The line runs under a road. I am having trouble finding information related to design considerations for underground or buried piping. Any help with applicable codes, standards, or reference material would be...
