I want to calculate the flow rate of water through holes in a mesh.
In the following hypothetical situation water is flowing through a 13mm diameter pipe at a velocity of 3 meters per second and a pressure of 0.55 mega pascals. (I do not know the water temperature or the surface roughness of the interior of the pipe, or whether the flow is laminar or turbulent)
Inside the pipe is a mesh, also 13mm in diameter, 2mm thick. The mesh contains 69 holes, each hole is 0.2mm in diameter.
Is it possible to calculate (or perhaps I should say estimate) the flow rate of the water through each individual hole in the mesh?
I am assuming that the flow rate through a 0.2mm diameter hole will be less than the flow rate through the 13mm diameter pipe, but I don’t know how to calculate this.
