Investigating An Anemometer.

... Investigating An Anemometer I decided to investigate anemometers, because I wanted to look at different ways of measuring wind speed. I decided to build two different types of anemometers and test them to see which one was more accurate and which one would work better at different wind speeds. I looked on the internet and decided to look at cup and propeller anemometers. My first task was to look at how to build a cup anemometer and what is the best way of designing and building it. 1. "The three cup anemometer is recommended; this design has been shown to exert a more uniform torque throughout a revolution. The rate of rotation of the cups is essentially linear over the normal range of measurements, with the linear wind speed being about 2 to 3 times the linear speed of a point on the center of a cup, depending on the dimensions
