HM 150.09 Orifice and Jet Velocity Apparatus
Education / GUNT Hamburg / Fluid Mechanics and Hydrology / Fundamentals of Fluid Mechanics /


 A plexiglas cylinder is equipped with an adjustable overflow and scale which enables the height of the water column to be set and read accurately. 2 types of outlet nozzle can be compared. The trajectory of the jet can be traced using adjustable probes and recorded on a white panel. 
The water supply is provided either from the laboratory mains or using the HM 150 (closed water circuit).

Learning Objectives / Experiments
· Torricelli s theorem
· Discharge coefficient from nozzles of varying sizes and shapes
· Trajectory of the water jet for various discharge velocities
· Effect of the height of the water column on discharge velocity
