The reaction wheel, either the Francis or propeller type, is turned by the fall of water through a duct or pipe in which the wheel is confined. For example, if the depth over your stake is 5 3/8, follow oer 5 (fifth row) to 3/8 (fourth column), and read the value as 5.01 cfm. With sound figures for both H and Q, you are now ready to calculate the available horsepower of your installation with the formula given in the first installment. and they want to scare people into thinking that they need to have a generator or a solar panel or something like that to survive.

Before you begin even a preliminary reconnaissance of water power on your property, the writer suggests you secure a looseleaf notebook to be devoted solely to the project. A major flood or storm event can make the flow and location of your water source significantly different enough to effect your power generation. Impulse turbines, which have the least complex design, are most commonly used for high-head microhydro systems. Stretch the hose or tubing down the stream channel from the point that is the most practical elevation for the penstock intake. All that water produces massive amounts of energy. Keep in mind that this would only be used to supplement your existing energy. Surely this generator will require consistent water flow, so make sure you have enough water available before purchasing.

Enclosed turbines are what most people go with because they are easier to get set up and cost less overall. . Back to Isaac Newton, to spin that generator takes energy of some kind which has to be of a greater strength than the minimum force required due to friction losses and other inefficiencies. Waterwheels are still available, but they aren't very practical for generating electricity because of their slow speed and bulky structure. But before you tackle the electrical side of hydropower, you need to understand something about the two basic types of electricity: direct current (DC) and AC. For example, if the depth over your stake is 5 3/8 follow over 5 (fifth row) to 3/8 (fourth coumn), and read the value as 5.01 cfm. Make a series of runs, averaging the results.
