Comparison of Pelton, Francis & Kaplan Turbine

In this video 3 most commonly used hydraulic turbines, Pelton, Francis & Kaplan are compared on the basis of their working principle and usability. Working of Hydro turbines are explained here with help of animation.

Precise and to the point explanation under 3 minutes. That's what YouTube is made for. Excellent Work. Keep it up !

[mumbles]

I'm glad I found this. Now, thirty five years after installing Francis type turbines in a dam, I know why they used them.

My long day confusion and doubt is cleared by this 3 minute video. GREAT EXPLANATION

[IvanIvanov-cxhj]

Thanks, I'll store that in my favorites incase I ever need this knowledge!

[adindasuci]

the explanation is very easy to understand, that way I am confident regarding the type of turbine that I will choose to use WWT in the future, thank you!!

[monazaidi]

Excellent and very informative video presentation. Thanks a ton! Please also mention the range of head and flow rate along with the graphs as those graphs represent the efficiency profile of these turbines at varying conditions..

Thnks for such a informative animated knowledge of use of turbines

le turbine Francis, Kaplan, Pelton sono le più utilizzate.
La Pelton è ad azione, il fluido viene direzionato su delle pale a forma di cucchiaio, che può essere singolo o doppio. È utilizzata ad alte altezze e basse portate. Ha un flusso tangenziale
La Kaplan ha la caratteristica geometrica, assomiglia all' elica del motoscafo, con pale svergolate esse lavorano a reazione, a basse altezze e elevate portate. Ha un flusso assiale
La Francis ha medie portate e altrettante medie altezze, la girante ha delle pale dove il fluido l'investe e genera muovimento. Ha un flusso misto

Interesting, I assume that this is also applicable to gases as well . So most fans are axial as are wind turbines (horizontal axis) and fans that develop higher pressure are listed as mixed flow (like a pump) .

[dbzhaim]

flow rate = Power/efficiency*water density*specific gravity*head
*if the problem is to choose what type of turbine to use
*but efficiency is not given, does it mean efficiency is neglected and cancel out?
*to determine what type of turbine you need H= head and M = flow rate to graph/plot

[dhavamanitechnologies-hydr]

great educational video, thanks, .
we manufacture electronic load controller of small pelton turbines(1-5kw)

[Asimyusree]

Tangential flow also called radial flow which means water flow perpendicular with the axis of turbine rotation

[gilbertobrazbotelho]

One Francis turbine in Itaipu Hydroeletric Power Plant in Brazil produce 971000 hp. There are 20 turbines in the plant.

[Mike-krdn]

Kaplan turbines can also be installed in lower flow rates close to only 1 m3/s

This must be the most dumbed down version of this topic.

Kaplan turbines can be used in several applications. Francis turbines are used because they are CHEAP. Kaplan turbines with their adjustable pitch can almost be as efficient as a Pelton turbine. The Francis will never come close but can be installed and run cheaply. That's why there are so many of them, mainly in China, India and other undeveloped countries. The Francis is the oldest and least efficient of the three.

Hi great video by the way ! May I ask for permission of how did you find articles of those graph for our research purposes

[DHARMENDRAGUPTA-orzw]

good one .i really appriciate your effort. Plz upload more video.

[abhishekmishra]

It was very helpful. Thanks for uploading👍

[Shumayal]

What would happen if we used Kaplan at a high head high flow rate versus low head and high flow?

[Omkar_.]

Nice sir
Make video on water boiler working
