The Francis turbine is an inward flow turbine that is the most efficient and widely used water turbine in the world today. It works best in higher head (pressure) applications, and hydroelectric power plants at big dams use these guys to make lots of watt-hours. The term "inward flow" means that the turbine itself (the thing with the blades that the water "presses on" to make the thing turn) has the water directed from the outside of the turbine wheel in onto the blades, and through them to a "center area" for the water to exit. The unit is darn efficient. Pictures are a mouse click away. Use the link to surf on over to our friends at Wikipedia (from which some of the data here was gathered) for more information and the cool pics that really show a viewer how the unit works.

Which is best for any industry pelton wheel or francis turbine?
francis turbine
Why draft tube is used in francis and kaplan turbine and not in pelton turbine?
The Kaplan turbine is a newer, more revolutionary version of the Francis turbine, which came before it. The draft tube is used so that the turbine does not need to be where the water flow is lowest.
When was Francis turbine invented?
1855
Difference between francis and kaplan turbines?
The comparison kaplan and francis hydro power turbine is as under: 1. Efficiency of Kaplan hydro power turbine is higher. 2. Kaplan turbine is more compact in cross-section and has higher rotational speed to that of francis hydro power turbine. 3. In Kaplan turbine, the water flow is axia and in francis trubine it is radial. 4. The runner blades in the kaplan turbine is less in number. 5. Specific speed of Kaplan turbine is 2 to 3 times that of Fancis turbine. 6. Friction loss in Kaplan turbine is less. 7. Francis turbine requires medium head while Kaplan trubines are low head hydro power turbines.

What has the author Francis S Stepka written?
Francis S Stepka has written: 'Analysis of uncertainities in turbine metal temperature predictions' -- subject(s): Cooling, Airplanes, Turbine-propeller engines
What is the differences between pelton turbine and kaplan turbine?
pelton turbines are suited to high head,low flow application but kaplan turbine are used for low head and a large amount of discharge needed. kaplan turbines are expensive to design,manufacture and install as compared to pelton turbine but operate for decades.
Working princieple of Francis turbine?
It is a radial flow axial turbine . It works on the principle to convert pressure energy into kinetic energy.
Why velocity of flow will decrease with increase in peripheral speed of francis turbine?
the peripheral velocity of the turbine is the around velocity. the increase in the velocity of the peripheral will decrease the velocity of the flow towards the turbine

What is the use pressure balancing pipe in the francis hydro turbine?
The pressure balancing pipe in a Francis hydro turbine is designed to equalize pressure differences between various parts of the turbine, particularly between the inlet and the draft tube. This helps to minimize hydraulic forces that could lead to mechanical stress or instability in the turbine components. By maintaining a balanced pressure, the pipe enhances the overall efficiency and reliability of the turbine during operation. Additionally, it aids in reducing cavitation risks and ensures smoother flow transitions within the turbine system.
What are turbine's used for?
Type your answer here... turbines are mainly used to convert hydraulic energy into mechanical energy.kaplan ,francis and pelton are the turbines.
