FLOW THROUGH AN ORIFICE

TecQuipment’s Flow through an Orifice apparatus allows students to measure: 

• Decrease in flow
• Contraction of the stream
• Energy loss

They find these measurements as water leaves an orifice. Students can also use the apparatus to study different shapes of orifice(extra orifices are available separately, H4a).

The apparatus works with TecQuipment’s Digital Hydraulic Bench (H1F) (available separately) and stands on the hydraulic bench worktop. The equipment has a transparent cylindrical tank, with a mounting in the base for different orifices. TecQuipment supplies the apparatus with a sharp-edged orifice already mounted. 

Water flows into the tank from the hydraulic bench through an adjustable diffuser. The flow rate and an overflow pipe set the water level. To change the level in the tank (and so the head on the orifice), students adjust the flow to the diffuser. Water leaves the tank through the orifice. The jet that leaves the orifice discharges into the hydraulic bench.

A Pitot assembly holds a sharp blade and a Pitot tube which students can position anywhere in the jet. The blade accurately measures the jet diameter, to allow students to find the contraction coefficient.

Manometers measure the total head on the orifice and under the jet. A traverse assembly holds a Pitot tube which students can position anywhere in the jet. A sharp blade accurately measures the jet diameter. This allows students to find the contraction coefficient.

If required students can download TecQuipment’s Hydraulics Data Management System (HDMS) software onto a suitable computer (not supplied) to aid with entering, evaluating and presenting their data. The HDMS is a complementary software tool designed to help students accurately record data from experiments associated with this apparatus. The software is intuitive and easy to use, with clear and convenient data display options, enabling students to run automatic calculations and export charts and results for further investigation.
