FM-1849-05 Orifice and Free Jet Flow Apparatus

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.

Specification

  • Unit for investigating the discharge from nozzles, for use with the Hydraulic Bench
  • Draining of a water-filled Plexiglass cylinder through a nozzle
  • Cylinder with adjustable overflow and scale
  • 4 exchangeable nozzles
  • 8 tracers and white panel to record the jet trajectory
  • Determination of:
    • Coefficient of discharge (Cd)
    • Coefficient of velocity (Cv)
    • Coefficient of contraction (Cc)

Description

A plexiglass cylinder is equipped with an adjustable overflow and scale which enables the height of the water column to be set and read accurately. 4 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 Hydraulic Bench.
