Sir, I have been searching for a youtube channel which will describe the complex functions and geometry of complex machines. Your channel gave me all these information within a short time. Thank you very much. Keep making these kind of videos. God bless you. Love your work.
Can you ask a question .. Hello sir, the smallest turbine, for example. 50 mica The number of meters of water you need per second ... What is the smallest turbine how much is produced in mica
Invented in Czech Republic, makes me proud because Czech inventors brought a lot of new inventions to the world, as contact lenses for example...also word "robot" was also invented in the Czech Republic...
Me parece un trabajo estupendo y un avance increible. Felicitaciones a la persona o personas que han realizado estupendo trabajo. I find a great job and amazing progress. Congratulations to the person or people who have done great job.
Aw, this was a really nice post. In idea I wish to put in writing like this moreover - taking time and precise effort to make an excellent video however what can I say I procrastinate alot and under no circumstances appear to get something done.
you all probably dont care at all but does anyone know of a way to get back into an instagram account? I was dumb lost my password. I would love any tricks you can give me.
@Raul Peyton thanks so much for your reply. I got to the site through google and I'm in the hacking process now. Takes a while so I will reply here later with my results.
To : Learn Engineering I hope you will explain about , Cross Flow Turbine , Turgo Impluse Turbine, tubular turbine dan bulb turbine. with your awesome animation 3d like have you upload. thanks
I have a doubt here. So, when water comes out from the draft tube into the open atmosphere, what makes sure that the pressure have come down to atmospheric level?? It it the length of the tube or the cross section ? if so then again there is more doubt. The flow rate and flow velocity is variable. If for a certain design, what happens if water enters at high speed (higher than the design speed).
Can someone please explain to me what is the use of the swirl casing for Kaplan turbine. If the end requirements for water entering the runner are to be axial and uniform throughout the perimeter, we can simply put the runner in the pipe from which water is entering the swirl casing. It would reduce pressure loss as well.
So here is a question, in almost all of the diagrams and videos I've seen, they always have vertical guide vanes, so as my family owns a hydro station for about 50 - 60 years, the first one in 1920's was Francis type with 3 turbines, after the Soviet rule once my family got the property back ( its was taken away because of nationalisation - no private property) we constructed a completely new hydro station with horizontal Kaplan turbine with 300 kw generator. Head is about 7m on low power and 5 m head with for example 6 m3/s would be max power. So our guide vanes are not vertical, they are horizontal but not exactly the guide vanes are about 20- 30 ish degrees against the exit tube, the turbine sits inside a concrete spiral room. So my question is what is the difference in having vertical vs horizontal guide vanes ( I beleave that in a horizontal setting it is Moore optimal for the angle of flow because water doest have to make a 90* turn
Very informative video, thank you. I'd like to know, if you were given a site that have low head and small flow rate, what type of turbine would you use? (besides waterwheel)
I'm thinking of using a jet ski pump drive, should I introduce the water flow thru the original intake? because the impeller blades pitch is reduced going towards the output, what do you think sir

Well, this isn't a great description how a Kaplan turbine works. The guide vanes for example, are newer pointing to the center, and the main reason with the adjustable blade is to have optimized trailing edge angle so the flow swirl component from the guide vanes are fully absorbed by the turbine. Half of the static head is converted to velocity when it passes the wicket gate (guide vane assembly) so the water rotates (swirl) when it enters the turbine, this swirl (contains half of the energy) is absorbed and the flow is leaving the turbine in axial direction. The swirl angle changes with the flow rate, so with fixed blade the turbine has a narrow band of best efficiency. So the main different between a Francis and a Kaplan is that the Kaplan has a much wider range of best efficiency owing the ability to adjust its blades and thus absorb the swirl, so 50% of head is converted to rotation that the turbine absorb and discharge axial, into the draft tube. When a Francis turbine operates at full load (BEP is usually 80% of full load) the swirl after the turbine is rotating the opposite direction and therefore the efficiency goes down. I'm an hydropower engineer and have worked many years designing Kaplan turbines at Andritz Hydro.
how about the draft tube? he said that it reduces cavitation, I think that's not the purpose of it, it's actually used to reduce the pressure at turbine outlet for more power generation and its divergent section makes sure that no back flow gets up from the tail race.
why we need water at inlet of vanes to be of uniform velocity ?. I know this is the function of spiral casing but if the water strikes the vanes with different velocity the turbine will still work . How will this affect the efficiency ?

The gap may too large between blades and wall.,but if we addon feed back to increase pressure when low density of air in space
.yet again..super
Thank you so much

Pelton and Francis Turbine
Very nice presentation , I want to have a similar video on turbine Governing which is a complicated subject.
very nice sir
You are the best.. I like so much your videos.. 👌👌👌👍
Thanks
Thanks 👍🍑
Awesome video, thank you sir
Tq sir very much
The blades are curved incorrectly for downward flow of water. The way they are shown will not result in lift, only reaction.
Perfect 3am video
Thankyou it's very useful.
good explained
Pls make video on Francis turbine also.
Very informative video, thank you. I'd like to know, if you were given a site that have low head and small flow rate, what type of turbine would you use? (besides waterwheel)
***** Kaplan turbine will be the ideal choice. Please see the video which compares different hydraulic machines.

Awesome explanation
How to understand the relative velocity what is the purpose of relative velocity
I'd rather hear a human talking.
You have to admit, this is better and easier to understand than when you call for tech support.
Very useful video ... Thank You
Good explaination. Thanks
May I know what generator is use for the kaplan turbine?
Nalla turbine.
super
very helpful and nicely explained..

Awesome video.. Thank you
Way of Learning 👍
Very good animation sir
thanks sir
Superb.
What is meant by absolute velocity and relative velocity
Absolute velocity (V) , Relative velocity (W).
Tanks sir
great work and thanks..
Not all Kaplan turbines have adjustable blades. Larger units have fixed blades.
Esas se llaman turbinas de hélice.
Do you have any source to confirm that?
Biscuit yes I do.....I build them for a living.
Biscuit well we can build a propeller/Kaplan unit that is adjustable however big they want but as a rule of thumb large diameter units are fixed blade
Fabián Sánchez Ramírez ahh I didnt know that. For me units with fixed blades were just propellers
Tnq @learnengineering

Sir Plz Aap hindi aur English me bhi explain kijiye
I was not able to buy ur subscription
what is guide vane angle?
165
what is cavitation
undesirable vaporization creats bubbles that damage the turbine elements...
it is explained at the vide named "how does centrifugal pump work"
