What is mouthpiece?

A mouthpiece is a short tube of length not more than two to three times its diameter, which is. fitted to a tank for measuring the discharge of the flow from the tank. By fitting the mouthpiece, the. discharge through an orifice of the tank can be increased.

What is an external cylindrical mouthpiece?

The mouthpiece is an attachment in the form of a small tube fixed to an orifice. When the tube is fixed externally, it is known as an external mouthpiece. Depending on the shape, a mouthpiece can be cylindrical, convergent, divergent, convergent-divergent, or of any other form.
