Abstract

Present paper shows the importance of theoretical power per unit volume concept in scale up studies in stirred tanks. Developed by Rao (1999), theoretical power per unit volume parameter, X is now a basis for scale up studies in stirred tank. The usual similitude either with Reynolds number or Froude number is singularly not valid to scale up the parameters of the stirred tanks. Interestingly X contains both Reynolds and Froude number. Two major numbers enough to describe any fluid flow phenomena. Present work goes deeper in the observation of X and based on the observations, it is said that X describes the dissipation rate of turbulent kinetic energy of the smallest eddies in turbulent flow. Representations on scaling ability of X have been shown by scaling the actual power consumption in square and circular surface aerators.
