With the same pipe diameter at the fan outlet, can the fan’s pressure and flow rate be made infinitely high?
Thread Content
The diameter of the pipeline at the fan outlet remains unchanged. If I keep selecting fans with higher flow rates and pressures, then the wind pressure and flow rate in the pipeline will also keep increasing – is there no limit to this?
It is recommended to get a book on \"Principles of Chemical Engineering\" to read; it is not very difficult. Most chapters can be understood with an intermediate level of physics knowledge. When fluid flows through pipes, it encounters resistance, and there are many details related to this resistance. To find out more about it, it is best to consult the sections in books that deal with fluid transport as a reference.
Every model of fan has certain parameter limits; I’m not sure why you keep increasing them
What I mean is, for example, with a sealing fan used to seal off flue gas at a pressure of 4.5 Kpa inside the wall box, a sealing air pressure of over 5.5 Kpa is required for the wall box; yet even when a sealing fan with an output pressure of 8 Kpa is used, sealing is still not possible due to excessive frictional losses along the flow path. So I was wondering if it would be possible to choose a fan with a pressure output of 15 Kpa, as that should help ensure sealing. Because, according to the intersection points of the fan’s and the pipeline’s characteristic curves, as the fan’s curve moves upward, both the pressure and flow rate at its operating point increase accordingly. So theoretically, for the same piping system, can I choose a fan with a higher output?
The total wind pressure of the fan is determined during the selection process; how could the pressure and flow rate be infinite?
