Question
A small model reactor is to be built for scale up studies of the behaviour of a proposed
large industrial stirred tank reactor having 1000 times capacity. The bigger unit of 2 m
diameter will have a liquid depth of 2 m. This will be fitted with a four bladed Rushton
turbine of 0.6 m diameter.
(i) Estimate the dimensions of the smaller unit
(ii) For the optimum stirrer speed of 330 rpm observed in the smaller model, what
will be the recommended speed in the industrial unit under the following
conditions
(a) Power per unit volume is kept constant
(b) Reynolds number does not change
