How Can Air Throw Distance for Fans Be Calculated?

[hosaf]

Hello Everybody.

I have a problem.

I study calculate air throw distance for FANs. How can I calculate it?

So I have some data below.

Fan Diameter
Volumetric flow rate (m^3/h)
Temperature
RPM
Power

Please send me note or documents If you have any.

Thanks for your help.

My idea about that;

0=ma-cv^2. But I am not sure it.

m:mass air rate
a:acceleration
c:constant
v:velocity

you can find cv^2 in http://www.sciforums.com/showthread.php?t=58458

I did some internet search and found only this.
Note that they say the formula is applicable for only "their" fans.

Maybe Ashrae has some info for HVAC systems regarding a single fan.

Thanks for your intertest.

As you motioned that formula given by Hartzellan Co. for only their Fans.

I try to calculate with Newtons First Laws (Motion in One Dimension or Two Dimension).

But I need coefficient of friction between air and air.
