Kukhlenkob} UDC 532.695 Experimental-theoretical investigation of the characteristics of a rotary-pulsatory apparatus with an impeller and controlled flow rate, which is intended to intensify the processes of extraction of substances from a vegetable raw material in the pharmaceutical industry, has been carried out. A semiempirical physicomathematical hydrodynamic model has been proposed; expressions for the characteristics of the averaged flow have been determined. Agreement between the calculated and experimental data on the head and the power consumption as functions of the flow-rate of the medium and the rotational velocity of the motor has been obtained. a}S.
