    Fan Manufacturer: 145W to Move 1kg of Air 1m

    Excellent, that's kinda what I thought! Is there a simple way/equation I can use to estimate the frictional forces and thus how much energy would be needed to keep the air going round? Thanks!

    Fan Manufacturer: 145W to Move 1kg of Air 1m

    Hi Guys, I'm sort of getting there but still am a bit confused. After thinking about what I am trying to do I have managed to define the overall problem as follows: Beginning with a large tube of diameter 1m and length of 100m that is formed into a circle so that both ends meet at a fan placed...

    Fan Manufacturer: 145W to Move 1kg of Air 1m

    I get it now, thanks! I think i'd better brush up on my theory!

    Fan Manufacturer: 145W to Move 1kg of Air 1m

    ...this is beginning to make sense now! I am actually trying to use the airflow to cool down a large area. The area being cooled is 1m long and I estimated the amount of air that I needed to transfer across the area being cooled should be 1m3 of air every second (i.e. 1kg of air). I thought...

    Fan Manufacturer: 145W to Move 1kg of Air 1m

    ...Thanks Bystander. In essence, I am trying to use a fan as an extractor. The air will simply be moved from one side of the fan to the other. I assumed that the energy required to move 1kg mass of air a distance of 1m would need 10J. The fan manufacturers state that their fan will use 145J to...

    Fan Manufacturer: 145W to Move 1kg of Air 1m

    Homework Statement Hi, I am trying to work out the energy needed to move a certain quantity of (ideal) gas using a fan but am finding a great discrepancy between my calculations and those supplied by the fan manufacturers. let's say i'd like to move 1kg of air (1kg/m3) a distance of 1m. I get...
