Orifice and Mouthpiece Apparatus
Product Code : JA-FMAHLE-9917
The Orifice and Mouthpiece Apparatus (SKU JA-FMAHLE-9917) is a self-contained hydraulics bench for measuring flow through small orifices and mouthpieces under a constant head. JaincoLab manufactures this orifice and mouthpiece apparatus for fluid mechanics practicals in civil and mechanical engineering colleges and polytechnics, where students calibrate each orifice or mouthpiece and determine its coefficient of discharge using the measuring tank, stopwatch and X-Y arrangement.
Specifications
Water is pumped by a self-priming monobloc centrifugal pump (30 LPM, 20 m head) from a 100 litre PVC sump to a 200 x 200 x 700 mm constant head tank fitted with the orifice or mouthpiece under test, and the discharge is collected in a 32 litre measuring tank.

Applications of the orifice and mouthpiece apparatus
The orifice and mouthpiece apparatus is used to find how much the real discharge through a small opening differs from the theoretical value, by measuring flow under a constant head, and it is a standard flow measurement practical in fluid mechanics and hydraulics laboratories.
- Calibration of orifices and mouthpieces
- Determination of the coefficient of discharge
- Comparing flow through 6 mm and 8 mm orifices and convergent and divergent mouthpieces
- Fluid mechanics and hydraulics practicals for B.E./B.Tech civil and mechanical engineering and diploma courses
