Finding theoretical output of my hydro generaator thanks.

    1. The problem statement, all variables and given/known data

    hey guys i have been undertaking a project on constructing a small scale hydro electricity generation system. I completed my project and was able to generate electricity using a turbine and a genrator, what i need to do now is find theoretical values for the electricity generated so i can compare them to my experimental values in my report.

    My experimental values :

    max output AC voltage : 4.4V
    max output watts : 0.066W
    resistance of coils : 10 ohms
    number of coils : 340
    length of 340 coils : 3metres
    current through coils : 0.015A
    magnetic field : i didnt calculate it, and i dont know the strenghts of the magnets although i can try find out tomorrow if need be.
    revolutions per second of generator shaft : unknown. (shaft is connected to magnets) and this is inside a box and then the outside of the box is wrapped in coils.

    2. Relevant equations

    ---- guys i am really lost here. i left my textbook at school and the equations i can think of are the emf equations f = bil , torque bia? i really dont remember. but yeah i am just trying to get some direction towards what i have to look for on the internet even or if i need to take more measurments from my generator.

    3. The attempt at a solution

    ------ thankyou.
