A liquid of density 950kgm3 and viscosity 250cP is to be mixed in a tank using a 0.61m diameter six blade, flat blade disc turbine, rotating at 90rpm. (i) Calculate the theoretical power for an agitation system conforming to the standard baffled tank configuration. (ii) Calculate the theoretical power for an unbaffled agitation system otherwise conforming to the standard tank configuration. For this configuration =1 and =40
