The field of electronics is a branch of physics and electrical engineering that deals with the emission, behaviour and effects of electrons using electronic devices. Pitch: Is the displacement a propeller makes in a complete spin of 360° degrees. This means that if we have a propeller of 40 pitch it will advance 40 inches for every complete spin as long as this is made in a solid surface; in a liquid enviroment, the propeller will obviously slide with less displacement. The propeller diameter has a big impact on performance. This fan type, shown below, generates high airflow rates but, creates low pressures so, is very limited to extensive ductwork application. I am currenty working on a KA4-70, however the geometry is not correct.
