Pitch may be the theoretical forward distance, in inches, that a propeller travels in the course of 1 revolution. There is always some “slip” involving the propeller plus the h2o (frequently ten to fifteen percent) so the particular length traveled is rather fewer than the theoretical benefit. think about pitch as velocity, or as here being the gear collection on an auto’s transmission.
