Venturi flume diagram
The Venturi effect is the reduction in fluid pressure that results when a fluid flows through a constricted section (or choke) of a pipe. The Venturi effect is named after Giovanni Battista Venturi
(1746–1822), an Italian physicist. The Parshall Flume acts essentially as a constriction, a downward step, and then an expansion: the upstream section is uniformly converging and flat, the throat is a short parallel section that slopes downward, and the downstream section is uniformly diverging and slopes upward to an ending elevation that is less than the upstream starting elevation. of Reclamation, Water Measurement Manual, should be used. That equation is: Q = 4.28 C e Tan(θ/2)(H + k) 5/2, where Q and H are as previously defined, θ is the angle of the v notch, C e is the effective discharge coefficient, and k is a head correction factor. The diagram at the left is a graph of C e as a function of notch angle, θ, and the diagram at the right gives k
as a function of θ. ISA SYMBOLOGY. The symbology for the identification of the measurement and control instrumentation on the flow and process diagrams and on the P&ID (Piping & Instrument Diagram), commonly called P&I (Piping & Instrumentation), is generally compliant with the
Standard ISA (Instrumentation Society of Automation) identified as S.5, that is composed of identification codes and graphic symbols. Related Topics .
