Claims (1)
流水の速度を測定するピトー管であつて；動圧孔
および静圧孔が穿孔され、その水路に没する部材
の流水方向に対する両側面は流水抵抗が少ない形
状に形成し、かつ上流面は流水方向に対して傾斜
面にするとともに、動圧孔先端を前記傾斜面に流
水方向に開口し、静圧孔先端を下流面に流水に直
角方向に開口したことを特徴とするピトー管。 A pitot tube for measuring the speed of flowing water, with the ends of the dynamic pressure hole and the static pressure hole immersed in the water channel; Both side surfaces are formed in a shape that has low water flow resistance, and the upstream surface is an inclined surface with respect to the direction of water flow, and the tips of the dynamic pressure holes are opened in the direction of water flow on the inclined surface, and the tips of the static pressure holes are formed on the downstream surface. A pitot tube is characterized by its opening perpendicular to the flowing water.
