I am making a testing facility for pumps. This facility has to be able to handle 500 m3/h with at little turbulence as possible. The basin itself is 5 meters long, 2,5 meters wide and 2 meters tall. The water level in the basin is kept at 1,9 meters.
The basin is designed in two sections: the first is where the discharge flow comes into the basin (pipe ends about 1 meters in from the bottom). In that area the water flows freely.
After that it has to flow over the retaining wall (1.7m high), which should create a somewhat uniform flow.
Are there better solutions to do this?
One other idea I have is a retaining wall somewhat like this:
This makes for three plates with cutout stripes.
The idea behind this is to have a more uniform flow across the entire basin instead of a overflow, making it create a small bit of turbulence there.
