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. TECHNICAL SPECIFICATIONS 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 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
