The purpose of this thesis was to study fluid mixing by determining impeller pumping capa cities from measured velocities in a mixing tank. Mean velocity measurements were made with the use of a Laser Doppler Anemometer (LDA) . The LDA was operated in the dual beam mode, with polystyrene spheres as seeding material. Studies were conducted with a 6 blade radial impeller and a 3 blade axial impeller. From velocity measurements, impeller pumping capacities were calculated for the above impellers. Impeller pumping capacities are correlated for varying impeller speeds at various measurement positions. The obtained results have been compared to published results under similar conditions.
