A purpose of this study is to manufacture a jet flow equipment in cheapness and small size. At first we manufacture this equipment experimentally for student experiments and. as a result. we manufacture official approval use and a small size jet flow equipment for studies. The acquisition target of student experiment with this experimental equipment is to learn a principle of the Pitot tube which is a method of a guide of the speed measurement and the directions for use. I manufactured a small size jet flow equipment by this study and investigated the performance by the speed measurement by a Pitot tube.
