Thought I would do a fairly simple calculation on a four blade fan I was lo=
oking at to figure out the CFM at several different RPM=E2=80=99s.=20
At my age I have learned to ask for help when things don=E2=80=99t look rig=
ht.
Can someone check my results on this and let me know?
Fan pitch=3D 1-1/8 inch or 0.09375 feet
Fan overall diameter=3D14.75 inches or 1.23 feet
CFM @ 700 RPM =3D3066 CFM
CFM @1000 RPM =3D4380 CFM
CFM @4000 RMP=3D 17520 CFM
Thanks
Perry
