The amount of work you put in it is big, both constructing the pump and making this video.

I bet you learned a lot from your little experiment. Try running your system with your black sump full to the top increasing pressure on pump inlet. Your not getting real cavitation, but dissolved oxygen is coming out of solution and extra height may help give you more NPSH. Great video, keep them coming!

@robertf1720 4 года назад

something something balance impeller Also 12:50 cavitation is when the dyanmic pressure is less than (flashing) then greater than (bubble collapse, micro water hammer) the vapor pressure of the liquid. In fact, in some rare cases, air can be injected to reduce the effects of cavitation because it keeps the vapors from collapsing. Overall fantastic video!

@flixerstudios1862 Год назад

Cavitation is something else than air bubbles. Cavitation occurs when the pressure goes below the vapor pressure of the liquid. The fluid then basically starts boiling creating small bubbles that collapse on impact. It's the cause of pitting.

@MrBucidart 4 года назад

You need a vacuum gauge between the source of water and the pump and a pressure gauge between the pump and ball valve. Thanks for the vid.

@mostirreverent 2 года назад

Also how does the shape or profile of a bane affect flow (i.e. uniform versus tapered or airfoil shape). Of course you would have to machine the impeller to use non-uniform profiles

To make cooling more efficient if wager having it flow onto a screen to disperse water and limit the air that gets into the water.

@hakachukai 4 года назад

From the start of the video I had one question that never really got answered. How did you keep the bearings and the drive shaft from leaking? I see that you used sealed bearings, but I bet they still leak. Cool video! Thanks for showing us this cool tech!

@EngineeringMindset 4 года назад

They did leak, but could have put some waterproof grease in there to stop it.

@hakachukai 4 года назад

@@EngineeringMindset Thanks for the reply! I'll keep that in mind. As a side note, I think it would be awesome if you did a future video on DIY shaft seals, testing various different methods to see which one works the best. Because when it comes to DIY seals, shafts seals are pretty much the holy grail of sealing techniques, right?

@EngineeringMindset 4 года назад

Originally I was going to use a spring with some packing to form a seal but for the amount of time it would take, I just simplified it as much as possible so that someone else could take the designs and build their own. If the videos is popular then I'll look at more improvements

@steve-o6413 4 года назад

Sounds like buying a pump housing is the way to go without leakage problems, but your visual video illustrates what the mechanics are for a pump housing. Time and materials are one thing, but a on going problem is the pits...

@saibalaji9024 4 года назад

Hu bro, I saw your videos, Its very useful to understand all the major concepts, Am having one request to you, I need to know about the estimation of power for a certain equipment, For Eg. I want to make a solenoid actuator, But I don't know how much of coil I have to taken for 230v and also know to estimate the power, please make a video, It may be useful for lots of Students

@expressionoffreedom7165 4 года назад

It seems like if you combined the cooling with desalination for fresh water you could make the whole system more efficient.

@mostirreverent 2 года назад

What I would say is that you did the right thing by building a physical test model rather than simply rely on the software. Physical testing is an important sanity check on simulation.

Can you make video on positive voltage vs negative voltage? How you can connect two 9 volts batteries for example in series and have +9 volts DC on positive terminal and -9 volts DC on negative terminal with middle terminal serving as common/virtual ground. What are the uses of negative voltage? Can you power a LED or 9 volts motor by connecting to -9 volts terminal and virtual ground terminal? Also since voltage is pressure, does negative voltage mean lower pressure and positive voltage mean higher pressure?

Bernoulli equation (or Conservation of Energy). The kinetic energy of the water has to go somewhere so it turns into pressure.

Obviously you enjoy building these sorts of things, but perhaps a more economical way is just buy a water pump for an old chevy 350 engine. Hook up electric motor to the pulley. The pumps can be had for like 15 dollars or whatever a junk yard might have. What I'm slightly more interested in is how the cooling works. Would there be an efficient way of making such a system work in a typical house?

Maybe a stupid question but.. What is the purpose of bearings? I know bearings are used a lot, and I know it usually involves something spinning - but I don't quite know the precise use for them. Maybe I'll find out in the rest of this video, in which case I'll delete this comment.. Love the videos!!

@EngineeringMindset 4 года назад

They allow low friction rotation of for example a shaft. That allows it to spin faster with less input power. Otherwise it would rub against the case causing friction and heating which will waste lots of input energy as well as wearing the shaft out very quickly.

@Chocoholic1337 4 года назад

@@EngineeringMindset Very cool! Thank you for answering my question.

@akay435 4 года назад

You totally skipped the inlet outlet conditions part in CFD setup. That is the most confusing part for even most experienced engineers to translate real world conditions into computational variables and making accurate assumption. Hope you'll cover it some day in any other video.

@celtman1213 3 года назад

this is a "closed-loop" system, the water returns to it's source. an "open" system would drain the water away without refilling the reservoir

@Heatherder 3 года назад

It is open to atmospheric meaning it is an open system. Whether the working fluid is recycled or not is irrelevant.

@CMZneu 4 года назад

12:37 I may be wrong but i don't think that can be called cavitation, i don't think the design is efficient or powerful enough to producer such low pressure to make water boil, at the very least not enough to produce any damage to become a problem, they are just bubbles sucked in through gaps and air dragged by the aerated water.

@EngineeringMindset 4 года назад

Yeah it's not true cavitation and isn't causing harm to the pump, but the bubbles reduce the performance quite significantly
