ASK THE EXPERTS: Running a Well Pump OffGrid | Home .Neither the well depth nor the depth of the pump have anything to do with the required pumping power. The determining factor is the water table (and desired flow rate). 1/3 HP is typically fine for wells with a shallow water table, for example, 30 or 40 feet.

Wind Turbine Final Royal Academy of Engineeringof any design of wind turbine is ( no more than 59% of the energy carried by the wind can be extracted by a wind turbine). This is called the "power coefficient" and is defined as: C p max = Also, wind turbines cannot operate at this maximum limit. The C p value is unique to each turbine type and is a function of wind speed that
