  • Height of air duct inside a warehouse

    What should be the approximate height of a supply air duct inside a warehouse whose side walls are 6 meters high and racks for storing goods would be 5 meters high. I am more interested in knowing the height if air diffuser grille from FFL is this warehouse. Thanks

    Re: Height of air duct inside a warehouse

    I am no expert here, but it seems to me that keeping it up high enough so it is not taken out by a fork lift, would be the proper height,

    now I am not figuring out what is FFL stands for?

    FFL Fixed Floor Level (architecture/building) ?

        I don't know where Ksa is so can't really help you out but generally speaking this sounds like something that the A/E should be figuring out on his own. The minimum height that the diffusers can be located without interfering with operations within the space that it was designed for is not dictated by any code that I know of. Diffuser height will affect air distribution patterns and velocity it would seem to me.

              as a mechanical engineer, shouldn't this be part of your area of expertise? i mean, shouldn't you already have the tools someplace to give you this reference?

              from Wiki:

              Mechanical engineering is a discipline of engineering that applies the principles of physics and materials science for analysis, design, manufacturing, and maintenance of mechanical systems. It is the branch of engineering that involves the production and usage of heat and mechanical power for the design, production, and operation of machines and tools.[1] It is one of the oldest and broadest engineering disciplines.
              The engineering field requires an understanding of core concepts including mechanics, kinematics, thermodynamics, materials science, structural analysis, and electricity. Mechanical engineers use these core principles along with tools like computer-aided engineering and product lifecycle management to design and analyze manufacturing plants, industrial equipment and machinery, heating and cooling systems, transport systems, aircraft, watercraft, robotics, medical devices, and others.

                I'm not clear if the OP is someone in the field related to the question being asked but in general engineering is a vast subject and even within a field such as mechanical engineering there are people who specialize in one thing and may not have much knowledge of another. Here is a simple example - an electrical engineer who designs high power motors is highly unlikely to know rf theory and how to design antennas for satellite equipment.

                        Its more likely that the caliber of the person asking for help is not up to professional standards.

                        I guess we all look at thinks differently, but I think in general here in the US of A we expect someone to know something about their trade (or that slice of their trade or profession) for which they are being paid to do work. A student or apprentice is different, they are expected to not know much about their craft in the beginning and expected to have many questions for which they deserve intelligent answers from those they are working for. That's all part of their learning process on the job and in the classroom.

                        But generally speaking, by the time you graduate from college with an engineering degree or become a Journeyman, you are expected to know enough to do most of commonplace parts of your trade well.

                        As with engineering the pipe trades have highly specialized areas that some will never get exposed to and others will spend their whole career working in and never plunge one toilet or install one AC unit. I don't use those examples to diminish their importance they are just two more common activities in the trade than say performing x-ray welds on high pressure steam lines or assembling those booster rockets for the space shuttle (yeah, there were pipefitters working on those things believe it or not). That does not make them incompetent and this is what blue can is saying I think.

                        However, I have to differ with him in this case and say if you are here asking questions which would be better but to your peers or in doing some research for yourself instead of relying on strangers on the Internet who you have no idea what the skill or knowledge level is then you are swimming in uncharted waters and better head back to the dock before you drown or get someone killed.

                          I do not know what the code book says here, but I would guess it has more to do with clearance than some height off the floor,

                          Code or no code, as I said before and I think it is a NO brainier, your duct work will have to clear the machine traffic (forklift) or that is my guess as you have 5 meter tall shelving, or about 15 foot tall, you only have about 3 foot (meter) of clearance and not even that if the top shelf is loaded up 3 feet, with product,

                          IF the Code would say 3 meters it will soon be 15 meters as it will be tore off by the forklift,

                          and I really doubt if the codes in your country are the same as here, and would have more to deal with air exchange than duct height,

                          and I see you got the same answer in two other forums, on the fork lift clearance,

                          I posted a few pictures of what is called a box store (wear house store), and in this type of store they use some small lifts but most product is less than 2 meters off the floor, so it is self serve, and you can see the ventilation is up in the roofs structure, probably 5 to 6 meters off the floor level,
                          (if there is a code these buildings would have been built to code) If there is a drop on the duct it may be at the walk in entrances,

                          the last one is a wear house lumber yard, you can see the venting system in the picture and how it is tucked in the roof supports,
