Zusammenfassung:	An apparatus, method and computer program product for controlling flushing in rock drilling, and a rock drilling rig. The apparatus comprises a control unit (CU) and a computer program (22) for controlling feeding of liquid component (LC) in air mist flushing system in response to detected penetration rate (15) of executed drilling. An operator (22) may set a desired moisture target value (16) for drilling cuttings (19) removed from a drill hole (12) and the control system automatically adjusts the flushing system to control the feeding of the liquid component.
