The Venturi scrubber is being used successfully for the removal of micron and submicron particle matter, both in solid or liquid state, from gas stream. From a practical stand point the most important item to be considered in the operation of the venturi scrubber is the amount of power required by the over-all pressure drop across the unit. A scrubbing liquid is introduced at the throat at zero velocity in the direction or gas flow. The work done in accelerating and atomizing this liquid is reflected in pressure drop. In the present paper, the pressure drop at the throat of venturi scrubber has been studied theoretically and experimentally. The additional pressure drop owing to the liquid injection is proportional to the ratio of liquid to gas and to the square of gas velocity at throat. The acceleration of sprayed particle has almost accomphished its function within a distance of about 20 cm from the injecting point.
