Sample Memo Use Of Company Vehicle
mini turbine you need to know
first thing you should know is the maximum power you can have Kilowatts, midas first flow of your stream, and of course if you have a fall of 5 meters is good, but the higher the better drop that is going to give you the speed at which the water will come down
For altitudes lower than the speed reaches 20 meters below the water will
raizcuadrada
V = (Vr ^ 2 + 2GH)
As the speed Vr of the river and the height H, g the acceleration of gravity
if I called the bucket or blade turbine where the water will boost the power output in the same will
P = 1 / 2 * ro * V ^ 2 * A * r * w
ro is the density of water normally is 1000 kg per cubic meter fall speed V calculated before, r the radius of the turbine and w the angular speed of the FIRO radians per turbine second to pass rpm using the formula
rad / sec = rpm * 2pi/60
with pi = 3.14 ...
if you drive at 50 Hz 3000 rpm will
Ponele numbers of these formulas with actual values \u200b\u200bmidas and ready to use and you know in advance the maximum possible power in kilowatts
You also know that there are other ways to better use today the streams as it ever going to lower your rate or to be dry, while other sources, such as the atmosphere and stores electricity in the ionosphere is endless, here you have people draw energy from there and more than for a home, hundreds of kilowatts or more with simple antennas
