Orifices, Mouthpieces, Notches and Weirs topics include: Orifice, notches and weirs classification, large orifice flows, discharge over notches or weirs, time required to empty reservoir with notches and weirs. In fluid mechanics, an orifice is a plate with a round hole in the center that is inserted into a line. Orifices are used as fixed throttles that create head loss. The head loss caused by an orifice can be used to determine the volume or mass rate of flow during flow metering.  Here are some other fluid mechanics concepts: Mouthpiece: A small tube or pipe attached to a tank's...
