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.

Experimental Content

• 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
