The comments made by Professor Joshi are a most welcome addition to the findings presented by us (Fort et al., 2010). We agree that many valuable studies in the past dealt with experimental investigation of turbulent velocity field in stirred systems with axial high-speed impellers. Therefore it would be highly desirable to present a comprehensive comparison of the efficiency of various types of impellers, especially for their optimum design for processes in chemical and biochemical industries. Nevertheless in such a comparison it should be taken to consideration the quality and reliability of experimental data, because both chosen experimental techniques and selected independent variables (position of impeller, viscosity and density of agitated liquid, etc.) have to be well defined and comparable in all investigated stirred systems.
