Hi Russ,
Will get in touch with you via mail. Will put the description into drawing to show you what I trying to do and hope to get the right way to calculate.
Will do that after knock off from work.
thanks
Hi I'm back. Based on the formula, I got a number 7103. (240rpm x 3kg x 9.866 - to convert to Newtons ,I suppose)
I hope someone can enlighten me.
What does the 7103 means? Power ?
If I keep this power generating for 1 hour, does it mean I get 7.103 kwh of electricity?
I hope its true...
Thanks Russ for pointing out my errors.
I will find ways to measure these factors (rpm, torque) to calculate the power that can be generated.
Thanks to all for your kind and valuable inputs. It helped me a lot.
Thanks for the above guidance.
I have prototyped a small buoyancy device which can produce a constant rotational force of about 4+ kg based on current size ( expandable depending how many tube I add) . The force was measured using a spring gauge i borrowed.
This device will keep turning a...
Thanks Bob for your reply. Although the answer was not so direct, but now at least I got some idea how to compute it to my applications. Appreciate your sharing.
Cheers,
Many sites describe their windmills in terms of wind speed, minimum or max etc.
Can anyone share with me how much force in terms of how much torque or kg force is needed to get it rotating? Is there any conversion formula to it? I'm sure different size of generator would require different force...
