The results of the experimental studies of the heat transfer from the verti
cal tubular coil to the pseudoplastic liquid agitated by mean of the high -
speed impeller in the vessel of diameter D = 0.6 m are presented in the pa
per. The measurements were carried out for the three coils and three impell
ers (Rushton, Smith, propeller) within the transitional regime of fluid flo
w. The study proved that the configuration: coil G2 - turbine impeller enab
les to obtain the greatest intensity of the heat transfer.
