Main Question or Discussion Point
i want to make a generator by rotating turbine by water... i want a equation for speed of the armeture and others plz help
If you want to make a hydro power project, the place to start is with your water resources. You need a flow of water running down a vertical distance.
How much water flow (liters per hour) do you have?
How much vertical distance (meters) does the water fall?
thnx .. but i can't find any suitable or understanding equation from there.. there is all projects and so on.. but I can't find the right formula or way to apply itGoogle is your friend. Good search terms to get started are small hydro generator. Since you are studying to be a civil engineer, a project like this is definitely in your specialty.
i know but i i want to creare a project for exibithion.. where i will need to work a 2Hp water pump ... i want to work on structure of water way so i need to know the speed of water then i can make the structure of water way..If you really want to build it, you must start with the numbers for the water, not for the electricity.
OK, that is more clear now. You want to learn about generator design. AC or DC, whichever is easiesti know but i i want to creare a project for exibithion.. where i will need to work a 2Hp water pump ... i want to work on structure of water way so i need to know the speed of water then i can make the structure of water way..
i want a equation for speed of the armeture
i need to create at leadt 2 hp power from the dianamo
A question well stated is half answered.
thnx very very much.... i needed just these things for my projects... i really wanted this equation and the types of information you just provide...
Here is a primer on motors. It introduces the concepts of torque and power which will be fundamental to your design effort.
It also touches on electromagnetics.
I think your starting point will be here:
horsepower = 2pi X torqueft-lbs X rom / 33,000
so your speed depends on the turbine with which you intend to drive your generator.
You'll have to pick a turbine size and speed from the volume and velocity of water that you have available at your turbine.
Here's a primer on hydraulic power of a pump. A turbine will be similar.

that should give you basic vocabulary.
Here's another primer on pump design.
a turbine is basically a pump with flow reversed.
Then look for a dynamo that'll do what you want.
To design a dynamo from scratch you'll have to become familiar with magnetic unts .
Unless you have access to a pretty complete machine shop, I'd suggest you adapt car parts.
Energy is conserved. So you'll have to extract at least 2hp from your water source.
2hp will move a LOT of water , so you're looking at a sizeable machine.
Go to the hardware store and look at a 2hp yard sprinkler pump.

An automobile torque converter has a turbine in it.
"Home Shop Machinist" magazine a few years back featured steam turbines made from them.
I suppose they'd work with water but i've never seen it done....would be an interesting project
I think you've bitten off a lot for a beginner.
You might look into a simple overthrow water wheel and car alternator driven with bicycle chain.
good luck. .
