Operating Behaviour and Characteristic

Over a wide range, this characteristic shows that pressure and mass flow rate are directly proportional. An extrapolation of this straight line would reach the 

5 = Diverging section p, = Motive pressure Po = Suction pressure 

For a wide range, no influence of the discharge pressure can be seen. This is caused by the supersonic flow in the mixing nozzle. Not until the increasing discharge pressure reaches the value of the critical discharge pressure, is the influence
