A pilot plant reactor, a scale model of a production unit, is of such size that 1 g charged to the pilot plant reactor is equivalent to 500 g of the same material charged to the production unit. The production unit is 2 m in diameter and 2 m deep and contains a six-blade turbine agitator 0.6 m in diameter. The optimum agitator speed in the pilot plant reactor is found by experiment to be 330 rpm. b. If the reaction mass has the properties of water at 70°C (ρ = 61.04 lbm/ft3 , μ = 0.48 cP) and the power per unit volume is to be constant, at what speed should the impeller turn in the large reactor?

Question
A pilot plant reactor, a scale model of a production unit, is of such size that 1 g charged to the pilot plant reactor is equivalent to 500 g of the same material charged to the production unit. The production unit is 2 m in diameter and 2 m deep and contains a six-blade turbine agitator 0.6 m in diameter. The optimum agitator speed in the pilot plant reactor is found by experiment to be 330 rpm.
b. If the reaction mass has the properties of water at 70°C (ρ = 61.04 lbm/ft3 , μ = 0.48 cP) and the power per unit volume is to be constant, at what speed should the impeller turn in the large reactor?
