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.

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. .
