Hydro power Definition and 11 Threads

I know the moment of inertia and the rotating speed of a shaft, and the allowable vibration is 2mm/sec. How is the force calculated? What is the formula to calculate the force on the shaft bearings which are a know distance from centre of gravity? Thanks

I've created a concept design of a subsea pumped hydro storage system, and need to use the flow rate in order to calculate power output. I can calculate the energy storage capacity using ##E = mgh##: $$E = mgh = 25675000×9.81×200 = 50374 MJ = \frac {50374MJ}{3600} = 13992 kWh$$ I've attempted...

Hi I am usually living off grid in simple huts in remote locations in Asia. A few months per year (rainy season) I don't have enough sun to produce solar power. I need very little electricity. My 20w solar panel produces enough electricity for my needs (lighting + charging a few small gadgets)...

Hydroelectric power, effected usually by damming a river, is ordinary considered an example of energy produced by gravitational potential. However, from an ultimate perspective, hydro power is actually an example of solar power. Water must drop to a lower gravitational potential to extract...

In theory or at least in my head, it seems simple enough to me. A simple water pump, such as a pool pump pushes water through a pipe into a water turbine and recycles the water directly back to the pump. With some of the hydrogenerators I've seen out there, they produce far more power than the...

Sorry if this is a bad question, but would lower costs to produce electricity (e.g. hydroelectricity instead of solar) bring down the overall costs for us consumers? Also, if there is any reading material or website on this topic, that would be really great too! Thanks!

Is Hydroelectric power plant a perpetual motion machine of second kind from this classification https://en.wikipedia.org/wiki/Perpetual_motion#Classification ? or not? If not which kind of perpetual motion machine is it? :)

I'm working on a project right now which requires a hydro turbine generator system requiring 120W of power output capable of working with the following specs: Flow: 0.003m^s/s Pressure: 6m head By my calculations, this should require an efficiency of ~66%. All flow must be in the axial...

Hi, I would like to know if it is possible to charge some batteries in this case: 4W output power, 5 V voltage DC in system that is shown in this video: Which is minimal power needed to charge batteries? Thanks

Could somebody please suggest me a staff mentor, or perhaps anybody, preferably a power system engineer and into hydro power. i really need some help. thank you :)

Hey guys, I am wondering what is the best type of mini hydro power plant to produce between 1 and 5Kw of energy. From what I understand most micro generator needs high head, and they take advantage of the relief (since power=head*flow*g) I am looking at an area where the head is very...
