WebOct 31, 2024 · A 2 = flow cross-section area at the orifice plate (m 2) Pressure loss due to orifice plate. In reality, there is always some pressure loss due to frictional effects when fluid passes through orifice plates. As a result, the fluid flow velocity (and flow rate) at the exit of the orifice plate is always less than what was calculated in the ... WebA 2D flow area is developed by first adding a new Perimeter. Then the user can create a mesh by bringing up the 2D Flow Area Editor, entering a base point spacing (DX and DY), and then generating cell points. After a base set of cell points are generated for a 2D Flow Area, users can refine the mesh by adding additional points, Breaklines, and ...
