Orifice & Mouthpieces Apparatus

The Orifice & Mouthpieces Apparatus is a versatile setup designed to determine the coefficient of discharge (Cd) for orifices and mouthpieces. It is widely used for experimental studies in fluid mechanics and hydraulics. The apparatus provides a practical understanding of fluid flow measurement through orifices and mouthpieces, enabling accurate calculations of discharge rates.

An orifice is an opening in the side or bottom of a tank, typically with a closed perimeter, that allows fluid to discharge.

Applications

Additional Information

A mouthpiece is a short tube fitted to a circular opening in a tank, facilitating controlled fluid discharge.

This apparatus is designed to experimentally determine the coefficient of discharge for both orifices and mouthpieces. It is equipped with mechanisms to measure discharge rates and other related parameters.
