    HVAC exhaust air temperature?

    I'm wondering what the typical temperature range of a multi-story office building or hotel's HVAC exhaust air is. I’m also interested in the volumetric flow rate, but I assume that more widely varies depending on the size of the system. I'm specifically looking at 7 to 8-story buildings in a...

    Am I doing these head loss calculations correctly?

    So, from a practical standpoint, even if the resulting air pressure coming out of a nozzle is just at or near atmospheric pressure, it can still have enough flow and velocity to mix a 330-L water/algae bioreactor? I know that as the pipe size decreases, the flow velocity increases, but at what...

    Am I doing these head loss calculations correctly?

    http://pastebin.com/30M0vhzF I’ve been trying to calculate the head loss of a plastic tubing air flow system, and I’m getting a very very high number for head loss for the 3/4″ inch section. Using the same method for the 2.5″ section, I was only getting 4.6 mm H2O loss/meter. 3/4″ is at 1,400+...
