How should I compute the efficiency?
Is this correct?
% = YgQh/Pout
Where Pout = Voltage x current
Y=density
G=gravity
h=head
Q= flow rate
Note: I don't need to have a high efficiency of the turbine. What I need is the efficiency of the generator itself.
How do I calculate the electrical...
So far i have learned that in order
To calculate the power input, I will use the P=mgh, right?
I still don't know what load should I used with 4.7 volts opej circuit output
I think it's okay to have a low volts since I am just going to compare the two. The problem is I don't know how to correctly get the input and output power in order to compare them
The LED of the flashlight gets busted when I manually rotate the turbine and the voltage reaches above 5V, which makes me think that I am using an incorrect load.
Honestly, the maximum voltage when I use a drill is 14V+ for the modified version and 10V+ for the unmodified one. Unfortunately...
When I had my Data gathering, I use a flashlight as a Load in order to get the current but the voltage output would only give as what I've said in the thread. That is why I'm asking the correct way of getting the power output by asking of the correct load to use or the correct computation of the...
I tested it using a drill as a prime mover and the output current and voltage increased. My problem now is to answer the objectives of my thesis, which is to compare the efficiency of the two generators.
