Hydraulic Studies and AccessoriesPitot Tube Apparatus
This apparatus is for a study of velocity distribution across pipe section for a water flow in pipe, and for measurement of flow velocity. It is to be used with Hydraulics Bench i.e. HB100 or HB100N (separately supplied).
The apparatus consists of a total head tube and a static head tube for the Pitot, clear acrylic pipe, inlet and outlet, and an inclined manometer. The total head tube can be moved up or down vertically with a scale for indication of the tube position. Differential pressure is measured by a multiple inclination manometer.
TYPICAL EXPERIMENTS- Accuracy of pitot tube meters
- Losses and k value
- Calculation of the coefficient of discharge
TECHNICAL DATAAcrylic tube 34 mm. diameter. Total head probe 1 ea. Inclined water manometer 0-450 x 1 mm graduation. Software for data display and analysis by computer (separately supplied). (0 reviews)
