Anemometer for pipe

Here, finally, the hands came to continue working with engines from hard drives. I made an anemometer for a pipe and now it is possible to evaluate the thrust from propellers of different profiles. now I will show how I made an anemometer, and in the next videos I will test different propellers and ask for interesting experiments.
Sit back and watch.
