Modifications to the Basic Equations

Flow Measurement – Small Orifices Consider the following tank discharge through a small opening below its surface: Flow Measurement – Large Orifices When studying small orifices we assumed that the head was effectively constant across the orifice. With large openings this assumption is not valid. Consider the following opening:
