Suppose I calculate on how much airflows (m³/s) I need to cool down a certain system, for example a generator. Now how to select a fan out from it ? The rpm of the fan depends on the rotations of the rotor since it'll be installed on the rotor. How to calculate the proper size of the fan to make this schematic works ?

great insight .. but I need a whisper quiet fan to move air through 25. 28mm i/d 85cm long tubes .

When you speak of static pressure is that the pressure across the fan or in the discharge? If in the discharge I assume the measurement is taken directly in the discharge?

Total System static pressure.

in your example of the restaurant owner wouldn't be changing the shape of the impeller (propeller) blower blade or whatever it is called, would't be that considered to make a change?

Not really because you still need to move an amount of air, the work has to be done and the pressure differential will always come in to play. But I'm sure the are optimal fan configurations depending on the requirement.

Hold the phone, wouldn't the restaurant owner want more vaccum pressure snd capture velocity at the hood instead of more cfm. Volume of air isn't the same as pressure of air.

on what factor of fan should i concentrate in order to remove the heat from the system? if i am pushing the air inside the system using axial flow fan

Yes sir this is what I'm struggling with on how to deeply understand fan working principle as a cooling device. Suppose I calculate on how much airflows (m³/s) needed to cool down a certain system, for example a generator. Now how to select a fan out from it ? The rpm of the fan depends on the rotations of the rotor since it'll be installed on the rotor. How to calculate the proper size of the fan to make this schematic works ?. Do you have any advice sir ?

Sir , if blower is coupled with motor ..can we adjust the speed ?
