F1-33 Pitot Tube Demonstrator
The pitot tube can be moved across the cross-section of the pipe in order to measure the dynamic head profile.
The pitot tube can be moved across the cross-section of the pipe in order to measure the dynamic head profile. The position of the measuring tip relative to the wall of the pipe can be read on a scale.
The pitot tube is connected to a pressurised water manometer to measure the differential head across the pitot static tube.
Inside diameter of test pipe: 27mm
Pitot-static tube outside diameter: 6mm
Pitot-static tube inside diameter: 3.2mm
Scale length of manometer tubes: 500mm
Cross section of manometer tubes: 5.6mm diameter
Range of pitot-static tube traverse: 21mm with 3mm scale increments
Requires Hydraulics Bench Service unit F1-10/F1-10-2
Features & Benefits
- Demonstrating the use of a pitot-static tube to measure the dynamic head produced by water flowing inside a pipe using a pressurised water manometer to measure the difference between the static head and the total head
- Demonstrating the relationship between static head, total head and dynamic head
- Demonstrating how a pitot-static tube can be used to determine the velocity of a fluid
- Demonstrating how the dynamic head of a fluid flowing inside a pipe varies with radius due to the development of a boundary layer at the wall of the pipe
- Demonstrating how the dynamic head profile varies at the entrance to a pipe downstream of a 90 degree bend with undeveloped flow
