Let me just see if I'm doing this correctly.
Fan specs: 95 cfm with outlet of 2-11/16 x 2-1/16 inches
Cross section area = 0.038493 ft^2
So the speed of the air would be:
95 cfm / 0.38493 ft^2 = 2467.99 ft/min = 41.1332 ft/sec
So assuming standard air density of 0.075 lb/ft^3 and...
not sure what you mean by velocity_from_fan
think of the object as a cart and the fan(s) are mounted onboard the cart pushing air backwards, thus propelling the cart forwards. The only information i have about the output of the fan is in cfm.
yes cfm is cubic feet per minute.
I'm trying to figure out what size fan to use for a project of mine, and I am given the number of cfm the fan produces. I'm wanting to use that to figure out how fast it can propell an object. since it will take 192 ft lbs to move the object, I figured I...
I'm trying to see how fast a fan that produces "x" cfm can move an object that weighs 150 lbs with a cof of 0.04. How would I set up an equation to find this?
Thanks
