Mugabe Posted January 8, 2018 Share Posted January 8, 2018 Can some help me on this please, desperately needs help, An open straight-blade turbine of diameter 0.82 m is used to stir reaction mixtures in a 20 m3 batch with baffles. The mixture to be stirred is composed of 15% NaOH solution with phenyl acetate reflux. Given that the power of the agitator is fixed at 0.52 kW, how many r/min of the turbine is possible? Given that Po = 1.07; density = 1890 kg/m3; viscosity = 1.2 Ns/m2 Determine: (i) The r/min (rpm ) for the turbine. (ii) Determine the emean value for the vessel. (iii) Would the agitation in the vessel be laminar, transitional or turbulent? Link to comment Share on other sites More sharing options...
studiot Posted January 8, 2018 Share Posted January 8, 2018 This cannot be answered without more information. The size and shape of the reaction vessel is required as well as the mixture volume. What is Po? What is an emean value? Link to comment Share on other sites More sharing options...
