Orifice plate Wikipedia

An orifice plate is a device used for measuring flow rate, for reducing pressure or for restricting flow (in the latter two cases it is often called a restriction plate). Either a volumetric or mass flow rate may be determined, depending on the calculation associated with the orifice plate.

Laminar Flow Forced Convection in Ducts by R. K. Shah and

In a fully developed laminar flow, the fluid appears to move by sliding laminar of infinitesimal thickness relative to adjacent layers. Depending upon the smoothness of the tube inlet and tube inside wall, fully developed laminar flow persists up to Re ≤ 2300 for a duct length L greater than the hydrodynamic entry length Lhy.

The flow was assumed to be fully developed at the outlet section given the large value of L/D. For this reason, outflow boundary conditions ((partial a/partial n=0,) where a is any hydrodynamic quantity and n the direction normal to the surface) were prescribed at that section. We verified that this choice leads to virtually the same steady

Entropy Analysis for Non-Newtonian Fluid Flow in Annular

In the present study, non-Newtonian flow in annular pipe is considered. The analytical solution for velocity and temperature fields is presented while entropy generation due to fluid friction and heat transfer is formulated. The third grade fluid with constant properties is accommodated in the analysis. It is found that reducing non-Newtonian parameter increases maximum velocity magnitude and
