An Overview of Micro Hydro and Power Production Calculations
Hydro power in USA, Canada and the World
Basically, It’s Solar Power
At the heart of the micro hydro system is a water wheel enclosed within a structure. These wheels can be of many forms. Listed are a few of the major types. high head medium head low head impulse turbines Pelton Turgo cross-flow multi-jet Pelton Turgo cross-flow reaction turbines Francis Pump-as-turbine (PAT) propeller Kaplan

These Turbines are turned by water. That turning motion creates energy by causing coils of wire to move relative to magnets. With the high head situations we commonly see in the mountains, pelton wheels and turgo wheels are commonly used. Jets are sprayed into cups of these wheels

Power Calculations • Power (watts) = Head (ft) * Flow (GPM) 10 Head 3. 28 feet = 1 meter Flow 15. 9 GPM = 1 L/S
Turtle Island • Turtle Island at high flow 300 GPM (1/2 of flow is 150 GPM) Head 140 feet (140 ft * 150 GPM)/10= 2100 W • Turtle Island at low flow 150 GPM (1/2 of flow is 75 GPM) Head 140 feet (140 ft * 75 GPM)/10= 1050 W
Mollies Branch • Mollies Branch at high flow 300 GPM (1/2 of flow is 150 GPM) Head 100 feet (100 ft * 150 GPM)/10= 1500 W • Mollies Branch at low flow 150 GPM (1/2 of flow is 75 GPM) Head 100 feet (100 ft * 75 GPM)/10= 750 W
