Orifice Meter Discharge - Application: Fluid Mechanics Lab Equipments

The Orifice Discharge accessory consists of a cylindrical clear acrylic tank which has an orifice fitted in the base. A traverse assembly is provided which enables a piton tube to be positioned anywhere in the jet. Attached to this piton tube is a fine wire which can be traversed across the jet to accurately measure the jet diameter and the vena contract diameter and so determine the contraction coefficient.
The piton head and the total head across the orifice are shown on manometer tubes adjacent to the tank. In addition to the sharp edged orifice six additional orifices with different profiles are supplied. All orifices have a common bore of 13 mm for direct comparison of performance.
