One of the best video about centrifugal fan education! An the animation looks very professional. Thanks so much! One correction, the voiceover keep saying the airflow measured in "meter square per second, m2/s", but it shall be in "meter cube per second, m3/s".
2:14 Clockwise or counterclockwise does not determine which way the flow is. What matters is the if the blades are LH or RH - and the majority of fan blades are optimized to turn only in one direction - they are not typically reversible. 2:30 centrifugal fans can develop much higher pressures than axial. 3:00 The animation has the impeller turning backwards. 4:00 it is pronounced "axis" not "access" and this is where I stopped watching...
If it's meters squared per second, then why did you put a 3 right there, as if you meant to say "cubed"? Actually, why wouldn't you just say "cubic meters per second" (like some people use cubic feet per minute)?
honestly just redo the whole video with 2k views you wont loose much and you can reuse the files of the cad models or whatever that is. just put it together the right way have things spinning the right way and get rid of the factual errors. to make this video you have to understand: how an airplane wing actually creates lift, the difference between bernoulli and ventury, accelerating and decelerating vanes, pulley ratios.
