studies are conducted to assess mix-ing in process vessels. Mixing time is defined as the time taken toachieve a certain fixed degree of homogeneity (say 99.5%) in thesystem (Figure 1). The experiment involved determination of mixingtime by pH method in a stirred tank (Figure 2 and Table 1). In thisexperiment, 1.5 L of double-distilled water was added to the tankand the initial pH [pH(0) at time = 0] was noted. A known molarityof sodium hydroxide solution was used as the tracer. 10 mL of tracer Figure 1. Typical plot of normalized pH vs. Time.was added and the pH value [pH(t)] was recorded every Figure 15 s using a pH probe. The experiment was conductedat a fixed rpm of 50
