Been a while since I've posted. So my hospital has erected a tent for COVID testing. The staff want it air conditioned. Any idea what the R value for waterproof fabric is? Has anyone got any tips or tricks for designing an A/C system for a tent?

Now that I got that out of the way, I have been asked if there is an efficiency advantage between 480V vs. 277V. Intuitively I said yes due to the lower amperage of the 480V, but I was then asked if I could prove it with numbers. At this point I am...
So I know that NIOSH specifies Grade "D" breathing air as follows:
(a) Oxygen (volume/volume) within 19.5-23.5%
(b) Hydrocarbon (condensed): no more than 5 milligrams per cubic meter of air
(c) Carbon monoxide (CO): no more than 10 parts per million (ppm)
(d) Carbon dioxide (CO2): no more...
Hello,
I have what I think is a quick question. I have a currently installed steam heat exchanger that I want to double in capacity. Per the design data I am only using 1/3 of the exchanger's capacity (U=180 but I am only using U=53 BTU/(f^2*h*F)). As I understand it, to squeeze the...
I need to justify the repair of a branch of an existing well water line in our plant. We are currently running city water to the areas this failed branch supplies and have meters to provide daily use requirements. I know what it's costing me to supply city water on a daily basis to these areas...
I have been tasked with designing a vacuum pipeline that will be connected to an existing vacuum pump. This is the first time I've delved into vacuum design. I've read about the term "conductance" and understand it to be akin to resistance. However, all the info I've uncovered merely...
