Hi gang. Can anyone point me to the math that determines the constant for the microhydro potential power ballparking equation? This one: flow x head / constant...
Dividing by 12 is probably more accurate, in my experience. The math for real? Go Google "wikipedia hydropower" "A hydropower resource can be measured...
Friend, please find as below Hydro Potential=(Weight density of water)*(Discharge)*(Gross Head) watt =w*Q*H watt where w is the weight density of water in...
