Description:
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. This is designed for use with the Hydraulics Bench and includes compatible connecting tubes. No additional instrumentation is required to operate.
Measurement Capability
- Demonstrating the use of a pitot-static tube to measure the dynamic head produced by water flowing inside a pipe using a pressurized 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
