Thanks for your replies again. I need to ponder about this for a moment...:)

But if you think of the turbine only and ignore the generator, then the angular speed of the turbine must be dependent on the water flow? I mean if you reduce the water flow by 50%, the force from the water on the turbine blades must be reduced and hence the angular speed of the turbine must...

Thank you for your replies! I see your point -that is perhaps the reason that hydropower plants often have several turbines/generators in parallel: if the water flow is low they will only use one turbine at near constant speed, while is the flow is larger they might add another turbine, also at...

I am trying to set up an equation relating the mechanical energy in a hydropower plant to its electrical output. What I picture is the relation between the energy input from the moving water, to the rotational energy of the turbine to the electric output of the generator. I know I can calculate...

I studied physics a few years ago, but feel a little rusty these days. I work with wind and hydro power and am interested in some topics related to that. Look forward to discuss and learn!
