[@eugenewong9101]

Good Day. I was wondering if you could help explain how to convert a 3phase alternator to single phase. Because I have 2 units of 5kv 3phase diesel gensets but most of my equipments runs on single phase. Therefore each phase couldn't take up much load. An educational video on the basics of alternators for gensets running at various RPM , number of poles, frequencies and it's associated pros and cons would be a great addition to your channel. Thank you.

Simply Fantastic. I am using a vacuum pump since 1978 it is only today-now that i came to know exactly how a vacuum pump works. How an agelong ignorance is removed within 10 minutes with the help of modern techno presentation. Thank you.

[@EngineeringMindset]

Glad we could help you out

[@Jewelrymaker]

Great explanation! Thank you. I never understood how a vacuum pump worked until now.

[@SickCotic]

As someone who is studying this right now to become a HVAC guy, thank you so much for explaining this is in a way that made is it simple to understand. Edit: grammar before morning coffee good is not

[@renoleceesay7869]

Wow! For a person like myself who knew nothing about a vacuum pump, this was extremely simple to grasp! Kudos!

[@charlie1a5]

Another very concise explanation for something that seemed complex Keep up the great work

[@EngineeringMindset]

Thanks, Charles. Glad you enjoyed

I just wanted to see the vane compressor arrangement - so perfect level of detail for me. Super video.

[@GMaXimus95]

These videos are life savers! Please never stop doing them!

[@chrisroberts3870]

Thirty years ago, for testing OEM air cond pipes and hoses, our engineering laboratory used a helium leak detector (small mass spectrometer optimised for helium) to assess the joints. It used two vacuum pumps plus a diffusion pump.

[@crudhousefull]

You are the absolute best! These videos need to be shown in every classroom around the world

[@omnious42]

That's so cool!! I have been binge watching your videos after I discovered this page several weeks ago now. I saw the HVAC school and after a few classes Brian mentioned he teamed up with you for this and now I am back here watching clips

[@LeOssiTrollterrible]

I just felt the need to research this and i have to say you are an incredible science communicator. I didn't have to pause at any point and understood everything you said. Maybe i am just dumb as hell but with physics videos this is almost never the case. Very well made!

[@axelasdf]

If you hook identical balloons together like that the smaller one is actually higher in pressure due to more elastic material per unit surface area.

[@EngineeringMindset]

That's a very interesting point, I like it

[@Firecul]

Thank you for saving me from typing this on my phone.

[@gunnarallgottsmann]

@ axelasdf And what you gone doo with the much greater surface from the bigger balloon? It’s just my question. Greetings from Belgium 🇧🇪. Peace ✌️

[@christianburger1456]

@@gunnarallgottsmann as the balloon gets bigger it's surface grows but the Material gets thinner. Therefore the tension gets less. Because the bigger balloon has less tension it's pressure is lower than the pressure of the little one and air flows from the little balloon to the big balloon. To experience this yourself just blow up a balloon. At first it's hard to produce the pressure with your lungs but at a certain point it reverses and it's easier to blow air into it the bigger the balloon gets. Hope that answers your question. Greetings from Germany🇩🇪

[@BillyBob-qu1fs]

They are also used in the Dairy industry to supply vacuum for the milking units. They are quite large. There are usually at least two vacuum pumps connected to a parlor. If one goes down the other one is used, or they are both used in conjunction to help take the load off of one unit. If the vacuum pump goes down the milking facility cannot function so it's normal to oversize the pumps so that one pump can run the system itself, albeit barely, or have a backup pump just in case. A small dairy farm (~50-100 milking head) will have pumps that are about 1' wide and 2' long mounted with a large ballast tank. A larger farm (~500 - 2000 milking head) will have pumps the size of engine blocks. This video was helpful as I have worked around these things my whole life and always wondered how they actually created vacuum.

[@bensdemosongs]

I have a pump with weak suction. No visible oil leaking anywhere, but I can feel air leaking out of the side seams- either where the pump or compressor sections screw into the body. Is this potentially a bad gasket or something?

[@vitorpera5853]

Great explanation! Thank you very much.

[@Cammi_Rosalie]

I have a vacuum pump, but never knew the mechanics of it. Now I know. Incidentally, it is the same mechanics that are in my hand-cranked fuel transfer pump, with the inlet being the tube on the bottom that goes into the bulk tank/drum, and the outlet being the spout on top of the pump. These pumps are nice because they are self-priming and reversible.

[@manikandanmadhuvappan8166]

Thanks for the explanation I have a doubt. How theblow pressure region and high pressure region gets separated. Please explain.

[@volt8399]

Thank you this was very educational

[@GraceAppliance]

Wonderful video! Thank you!!

[@tmst2199]

Wow. This is excellent. The dual units is a trip. So would adding a third increase force linearly? Hint: Not linearly, but logrithmically, approaching 0 at n = infinity. Nice touch adding the tip about heating the coil to extract more of the water.

[@nooahchannel]

Nice video. Good job my friend.

[@willl84]

The pumps I've rebuilt at work don't use springs to push out the vanes. They're just thrown out by centrifugal force. They also all have more than two vanes, typically 6

[@TinG-hz7fm]

Great video, except for the part with the baloons. Think how hard it is to start blowing a balloon, but once its big enough, it gets easier. Therefore, if one connects a big and a small balloon to a tube, the smaller one would deflate and the larger one would inflate. Of course if the smaller balloon was deflated it would inflate a little, but they would never become equal in size.

[@zeuspunz]

The thing that you talked about is a practical occurrence however Paul is talking of idealized balloons. In real life the latex balloons are made up of a nonlinear material - this means they do not deform (i.e. inflate) proportionately with pressure (blowing in). If the material was linear (or ideal) then you would get exactly what Paul said. Most of the engineering material taught at the undergraduate (and even MS level) is with linear material (or linearized systems) to keep things simple to understand. Hoppe that helps.

[@goodboy140386]

Super Nicely explained !! Thank you for such cool animation !

[@monkfry]

The ballon example in regards to the high side/low side pressure is a great analogy for explaining equalization. 👍

[@JayLikesLasers]

At 04:30 there is a mistake when you say "Pressure always flows from high to low". This is not true. Fluid flow has momentum, and can flow into regions of higher pressure by expending some of that momentum. It occurs over the top surface of aircraft wings, or in diverging nozzles for example.

[@omsingharjit]

How it sealed the chamber from front side because it should be air tight but this can jam rotation ? But how it's managed ?

[@CreativityUnleashed]

I recently purchased a freeze dryer which utilizes a vacuum pump for Long periods of time they recommend not to stay in the same room with the vacuum pump because of small oil vapor so I made a hole in the wall and extending the house how do you think a longer hose will affect a vacuum pumps ability to remove air ?
