Topics: Introduction Equations Discharge Coefficients Error Messages References. Introduction to Orifice Flow Meter Calculation. Orifice flow meters are used to determine a liquid or gas flow rate by measuring the differential pressure (P1 - P2) across the orifice plate. The two standard pressure tapping arrangements for small bore orifices are shown in the drawings; the location of the pressure taps affects the discharge coefficient somewhat.
then smooth boundary >100.Roughness in the term of reynolds number Instead of value of is used to classify the type of boundary and limits for these type of flow is <4. then rough boundary . Laminar Flow in a Pipe The behavior of flow in pipes is determined by the Reynolds number Re. .Criterion for Turbulent vs. Flow tends to become turbulent when Re > 3000. the behavior is unpredictable and often switches back and forth between laminar and turbulent.
