Of course, we used the wrong diameter for our circle! I can't do the exact measurement right now but I measured the straws we used and if i account for a certain amount overlap where the straws are connected, I think this diameter is approximately 4 times the diameter we used in our original...

Ah yes now I understand, so that is why we are getting such low speeds from our anemometer. Perhaps we can get around this by using a different meter for the wind speed? I know someone suggested also using a Savonius turbine and comparing the results from the two experiments. And now I see...

We divided by 60 because the article said so, we didn't really question it because it made sense since there are 60 minutes in one hour. However when I change it it gives me a more acceptable value of around 1.1 km/h for the lowest speed and 1.4 km/h for the highest speed. If we then take...

Homework Statement Hi everyone, I'm currently in my first year of college and today I tried to calculate the wind speed of a fan by using a home made cup anemometer. In our experiment we measured the time needed for 10 revolutions, on both of the speed settings of the fan. We then converted...
