how to calculate the dimension (radius, height and width of blade) of water wheel to produce 500Watt power gen View All
I am a student of engineering. My lecturer assigned me to produce a prototype of floating waterwheel river turbine that connected to a 3-phase permanent magnet generator. It is necessary for this generator to generate constant power of 500Watt to charge 12V battery. the water flow at constant speed of 2m/s. emf constant for generator I calculate is 0.06 V/rpm. Can anyone give me the formula for me to calculate the dimension (height, radius of waterwheel and width of the blade) of the waterwheel I need to built to get this amount of power.
