    It shows a large baghouse inlet ductwork. The inlet duct is tapered to minimize dust dropout. A shallow taper such at this also reduces pressure losses when changing duct diameters. Note the rectangular duct ring spacing is roughly 2'-6" on center. The round duct is stiffened near each branch duct.

    Plumbing systems also service air distribution/control, and therefore contribute to the mechanical part of MEP. Plumbing for HVAC systems involves the transfer of coolant, pressurized air, water, and occasionally other substances. Ducting for air transfer may also be consider plumbing, but is generally installed by different tradespeople. [11]

  7. Bell mouth - Wikipedia

    en.wikipedia.org/wiki/Bell_mouth

    A bell-mouth inlet duct is a form of convergent inlet air duct used to direct air into the inlet of a gas turbine engine. The area of a convergent duct gets smaller as the air flows into the engine. A bell-mouth inlet duct is extremely efficient and is used where there is little ram pressure available to force the air into the engine.
