    Calculating the Entry Area for a Funnel to Increase Air Speed

    hehe, no it's not in engineering unsurprisingly. I'm an architect and urbanist looking at peak oil, so sadly my knowledge of air flow, torque and that are a little lacking but that's exactly why I'm asking so when someone asks me, "Does this fantastic concept actually work?" I can say... "No...

    Calculating the Entry Area for a Funnel to Increase Air Speed

    Firstly, I understand all of your points and totally agree with them. I am however, doing a project for masters and testing theoretical potentials of energy systems. In this case I was studying how I might encompass a vertical axis turbine into a new urban form based around solely wind energy...

    Calculating the Entry Area for a Funnel to Increase Air Speed

    I thought, that if you increased the wind speed by funneling it then potentially the greater proportion of kinetic energy might i.e. since the air is now oving at 12m/s could turn my turbine more rapidly. Though I wasn't sure how the loss of potential energy would affect this. So, The increased...

    Calculating the Entry Area for a Funnel to Increase Air Speed

    Alright, Another question then. If I funnel air and increase its speed from 4.8m/s to 12m/s will it turn a wind turbine with increased force or will the resultant loss of pressure energy mean that the turbine will only turn as fast as if it were a 4.8m/s wind?

    Calculating the Entry Area for a Funnel to Increase Air Speed

    Hello! I've attached an image below that shows a simple diagram of my question. I would like to know how to work out the area that I would need for a funnel to increase the air speed from 4.8m/s to 12m/s. The exit would measure 25 by 25, how big would the entrance need to be? I've...
