| 520 | _aA tube viscometer was instrumented for monitoring the pressure drop and flow rate data continuously using specifically designed transducers. This led to the easy recording of reliable and as well as repeatable experimental data for studying non-Newtonian flow behavior of liquid foods. The pressure recording transducer was a disphrage type with strain gages mounted on it and suitably connected to a bridge circuit and an amplifier. For flow rate determination, a load ring was designed and used for recording the net amount of flowing material accumulated in a container placed over it. Later, the net material weight vs time plot could be used to determine the instantaneous flow rate for a given tube. The transducers performed satisfactorily ad their calibration curves indicated linear and reproducible relationships within the range of experimental variables. The log-log plot of shear stress vs shear rate at the tube wall for banana puree and tomato ketchup samples exhibited distinct linear relationships upward indicating a higher pressure drop for a given shear rate. There was no transition from laminar to turbulent for sugar solution, perhaps due to its higher viscosity. The slopes of shear stress vs shear rate curve (pipe flow behavior indices) of sugar solution were very close to unity indicating its Newtonian characteristics. The pipe flow behavior indices in laminar region had a lower values than in turbulent flow region for banana puree and tomato ketchup samples: the effect of tube diameter on flow characteristics could be accounted in terms of the slip parameters (and). The plots of slip parameters parameters vs shear stress were distinctly different for all tested materials and it was not possible to express these relationships mathematically in a general manner. | ||
