Help, on the flow flow design Venturi tube, would like to calculate the various positions of Venturi tube static pressure, I would like to ask how to import and export conditions, I own design, the entrance is the total pressure, exports to the environmental pressure, but when I changed the diameter of the venturi, the static pressure value change is wrong, ask the big god to guide
