Static pressure in ducts and vessel

  1. Jul 12, 2006 #1
    If air is venting thru a 10" duct and there is a static pressure drop of
    2” water column for every 100’ of length at 2000 cfm and the duct opens to a 1000 cubic feet airtight vessel and exits through another 100’ of 10” duct how can you find the pressure drop for the tank alone?

    Hi Gordon. You can add up the pressure losses for each individual portion of the system to come up with a total pressure loss. The loss for the tank, assuming it's large relative to the duct diameter, is only the entrance and exit losses. There's some discussion of that here:
