all the effort and amazing footage of these experiments - and you comment on the music ?????!!!!

@@thesnitch7 the music is lit af!!!

@@thesnitch7 All the effort of mixing ingredients to bake a cake and you comment on the frosting?! C'mon bruh! The videos are great and the music is like a beautiful capstone.

@@CausticLemons7 who said the music sucks? Not me. I love the whole thing.........bruh. BTW - thx for proving my point re:effort vs frosting - I agree 100%........bruh.

@@Pman353 yep. But it's not the main thing.

You are going to enjoy the Fan Showdown on the Major Hardware YT channel

How did he generate the smoke?

@@SandeepKumar-jj7zi some kind of smoke machine. It’s probably tiny water droplets.

WHERE STL

oh man i was expecting Ben from Applied Science to randomly show up

Except he's wrong. Exactly backwards. It's using less current because the resistance in increasing. It's harder for the rotor to spin because there's lower pressure on the inside but full pressure at the outside trying to rush in backwards. If he put his hand on the blades it would have the same effect - current would go down. For a fixed voltage current will decrease as resistance increases.

@@reginaldjeeves9825 An electric motor is not an resistive load. It contains coils of wire, solid pieces of metal, which current will just flow through creating a magnetic field. The fewer work that field does the more current can flow. The impeller not being slowed down by incomming air means it does less work.

Compressor engineer here, the current decrease has all to do with "suction throttling". What's happening is the restriction of air flow restricts mass flow. And the total reduction of mass flow is greater than the increased compression work (specific work done on the air). With suction throttling the Inlet velocity at the eye of the impeller is reduced but the exit velocity is not (it is relational to rotational speed) so for every gram of air the compression work is going up just not as much as mass flow goes down.

@@reginaldjeeves9825 except you're wrong since an electric motor is not a resistive load, but instead its an inductive load

"Horrible" depends on what type of person you are.

Yeah, you need unequal number of blades vs outlets, otherwise you end up with a siren :D

​@@akkudakkupl Yep Though there are some sirens that have 4 outlets but 10 blades or 10 ports, For instance, The CLM Siren. Another example would be the Thunderbolt series. With only 1 thin opening at the front

@@ctdcgaming2440 Well the more correct answer would probably be to have blades and outputs non divisible by a common denominator? For example two primes, or a prime and the same number -1 or +1.

@@akkudakkupl That's only to get a constant tone, I was mostly talking about the matching blade and outlet cutoff shape that significantly increases the noise because of pulsing.

Makes sense why you only get 10 to 15 min on max... still impressive as hell though. Now if I could only get my kids to put it back on the damn charger....

Have you got any plans/pictures of the converted Dyson?

@@wakefieldallan Yes, but compared to a regular 1800w vacuum, they are impressive AF

Even the dyson V8 is nothing compared to the newer V11s and V15 dysons

Thats pretty cool!

Cool! I've been wanting to do something similar for the shop at my work, homemade giant vacuum and hide it behind a wall with a hose coming out. Those big central vac motors are not cheap but I think if I found an old motor I could make something work. Maybe skin the 3d print with glass or carbon fiber.

@@deathcogunit106 Some years ago we just used small forge blowers in our woodworking factory for dust and shaving extraction. The missus sewed up a bunch of calico bags to collect the swarf; used to work real well ! Empty it into the compost heap(if not treated pine!)

That's just impossible O_O

The revenue seems to be over 10B at 10:04

Nice

the Conv. Rate was also lit!

its fudged data XD

But we need STLs

Would be interested in a lobe and a screw type too.

The miracle of motor back EMF

Please ask him to use his skills counter rotating on the US debt spiral clock $194500 per worker it is shows according to the vacuous wind bag OIG (Orifice of Inspector General)

That's how centrifugal impellers act. When you stop the flow, the air stuck in the casing is already up to speed, rotating with the impeller blades.

Right! 10 trillion dollars is no joke!!

@@getoffthegames89 Neither is a 420 percent conversion ratio

That literally _sucks_ - damn I mean Hoovers up - all the economic activity out of the country - all going on _plastic_ US debt is now $39 GOD Zillion

lolmy comment says "Cool stuff. Most turbomachines (non-positive displacement) reach peak pressure delta across them around their mid volume flow capacity. You could be quite far down the pressure capability in your static suction test. My bet is the turbocharger style would win out for suction per watt input. Your axial flow design has the most potential but you need pressure taps between each stage to ensure each one is doing its part. Did each stage have a different blade design?
