▶️Francis turbines are mixed flow reaction turbines. They are used in many hydroelectric plants because they can be used over a wide range of pressures and flow rates.
Pumped storage power stations use Francis turbines because the runner can act as both a hydraulic pump and hydraulic turbine.
How it Works
Water flows into the scroll case from the penstock. Water then flows through the wicket gate to the turbine runner. The water enters the runner radially and is discharged axially, because of this, Francis turbines are classified as mixed flow turbines.
After discharge from the runner, the water enters the draft tube then the tail race.

The graph at time mark 4:46 comparing Pelton to Francis to screw propellers was most informative. That was something not seen elsewhere and very helpful.

The guide vanes should be turned toward the francis turbine, how they are place in your graph, it causes that water crash againt them instead of going directly through the turbine following the curve of the vanes. This placement of guide vanes could potentialy cause damage to the turbine due to cavitation created by the lack of pressure.

Very surprising that the narrator is describing the water direction incorrectly, initially. Does he not analyze a video before posting it? Unless I entirely misunderstand this thing. I still give it a 👍

Hello. Great video! I am trying to build a hydraulic system in Africa where we use 220V system instead of 110V. I want to use the hydraulic system from a well or in tank to produce electricity. Which turbine do you recommend I use? I want to be able to power a fridge, A.C, washer, microwave all the heavy loads. Do you have a generator or runner in mind? Would I need a battery or an inverter? If so, what kind?do you inn is a co oany that sells hydraulic system altogether (turbine, generator, battery, inverter etc) instead separately? Sorry for all the questions. Thank you for your help

The first you need is a difference of height from were you take the water and the place you will pour it.. as more difference in height better.. do you have that possibilitie?

Runner is the only rotating part of the turbine. How is it connected to the non rotating parts? I mean it can't be hanging in the air.

Why does the turbine spin in the opposite direction to the water flow in the scroll case? Intuitively it would seem more efficient to have it spin with the flow so that's got me scratching my head a bit.

Why are there no multi stage turbines ?? Answer the tech is available from RDP MARINE AUSTRALIA The techs will say the issues are turbine surging OR to much backpressure OR the dissolved gasses issue ALL are nonstarters So were is the price drop you can have by fitting this item ?? YES YOUKNOW WHY
