    Duct/fan sizing over long distance

    Does anyone have an order of magnitude price estimate for the following: http://specs.topspotservices.com/hsi/downloads/246.pdf $100s of K, or millions? Thanks.

    Duct/fan sizing over long distance

    Hi SADK9, I like the way you are thinking about breaking the problem into parts. For a radial blower, I have not been able to find one with a capacity of more than a couple of thousand CFM. I need about 30,000 CFM. Is it still a reaslistic option? Am I looking at the wrong places? Thanks...

    Duct/fan sizing over long distance

    I am now considering a multistage centrifugal blower. I found this one from HSI as an example (PDF - http://specs.topspotservices.com/hsi/downloads/246.pdf). At my flow rate (50000 m^3/hour), it discharges 24 psig. I know this is an enormous blower and probably very expensive. I will have to...

    Duct/fan sizing over long distance

    OK, thanks. That's what I feared. I mean, if I have a 1 atm pressure drop, that is a lot of inches of water in static pressure from a fan. Hmmm...

    Duct/fan sizing over long distance

    Haha. 1.5 m was sort of a worst case scenario. "select fans and then design a pipe size to match the available pressure" <-- this is what I am not sure how to do. How to select fans? How does static pressure of a fan, or a fan curve, or any available data translate into how much frictional...

    Duct/fan sizing over long distance

    Hi Goober Dave, Thank you for the reply. To be honest, I am not sure what a typical static pressure limit would be. We have not specified the materials of construction for the pipe, but are considering corrosion resistant stainless steel and possibily even fiber glass options. Ideally, we...

    Duct/fan sizing over long distance

    Hi all, I'm working on a project which will move flue gas from a plant to a processing plant some distance away. In planning for a worst case scenario, we need to move the gas up to 10 km by pipe. Due to its properties and potential water content, high pressure transport is not an option...
