FS-1.3 Energy Losses in Bends


FS-1.3 Energy Losses in Bends

The Fluid Science Energy Losses in Bends Tray includes experiments to measures the pressure drop across, a smooth bend, a tight bend, a Mitre bend. All the pipe test section are of the same cross section, enabling meaningful comparisons to be made.

The additional energy losses due to the geometry of the flow path can be clearly seen at different flow rates and the relationship to theory can be established.


The Fluid Science FS-1.3 Energy Losses in Bends Systems Tray provides hands on experimentation designed to demonstrate energy losses due to the geometry of the flow path at different flow rates.

Utilising the FS-SU service unit the experiments rapidly mount onto the multifunctional work panel and is connected to the built-in water supply via quick connect couplings.

The differential pressure reading is taken using a digital manometer against varying flow rates.

The tray includes the following Hydraulic Circuits:
