WebJul 1, 2024 · If the pressure head at the throat falls below the separation head (which is 2.5 meters of water), then there will be a tendency of separation of the liquid flow. This is called the venturi vacuum. In order to avoid the tendency of separation at the throat, there is always a fixed ratio of the diameter of the throat and the pipe (i.e., d2/d1).
