Hello,
Can we estimate flowrate of a fan with its kilowatt and/or diameter and/or "water volume of it" ?
Thanks

RE: Hello, Can we estimate flowrate

If you have a manometer reading available at the discharge duct, (fan developed pressure) please use the following equation I have taken from Steam Plant Calculation Manual p-156 by V Ganapathy.\
\
BHP = q x Hw/(6356nf)
\where\
BHP Fan Break Horsepower HP\
q air flow acfm\
Hw developed head inches of water\
nf fan efficiency from fan curve\
further BHP = KW motor x motor efficiency typical 90%\
\
Hope this would suffice. Regards Ansari
