Answer 1

Dynamic similarity implies a correspondence of fluid forces for the flowmetering system. For inferential flowmeters, the velocity profile and turbulence level of the flow in the laboratory must be identical to the velocity profile and turbulence level of the flow in the field.

For turbine meters, the inertial and viscous forces are considered significant within the application limitations. As a result, the pipe Reynolds number (Re_D) correlates dynamic similarity in all empirical meter factors for turbine meters. If the gas composition, P_f, and T_f are relatively constant, then the volumetric flowrate at actual conditions (q_av) can be used to correlate dynamic similarity for turbine meters.

Dynamic similarity implies a correspondence of fluid forces for the flowmetering system. For discrete flowmeters, the fluid's mass density and viscosity in the laboratory must be similar to the fluid's mass density and viscosity in the field. For rotary displacement flowmeters, the volumetric flow rate at actual conditions (q_av), equivalent to V_avg, can be used to correlate dynamic similarity for rotary displacement flowmeters.Dynamic similarity implies a correspondence of fluid forces between the empirical artifacts and real-world installations. For orifice flowmeters, the velocity profile and turbulence level of the flow in the laboratory must be similar to the velocity profile and turbulence level of the flow in the field installation.

For the orifice flowmeter, the inertial and viscous forces are considered significant within the application limitations of this standard. As a result, the Reynolds number, which measures the ratio of inertial to viscous forces, correlates dynamic similarity in all empirical coefficients of discharge for orifice flowmeters. The experimental pattern was designed to explore sensitive Reynolds number regions.
