A six-blade turbine is used to agitate an aqueous solution (sp. Gravity 0.98, Viscosity 1.01 centipoise) in tank of 0.5 m in diameter and 0.5 m in height. Impeller diameter equals to one third of tank diameter. The tank is filled with four longitudinal baffles (0.1 Dt) and is filled to 90% of its volume with solution. i. ii. Calculate the value of shape factor S, and determine the power consumption if the impeller is operating at 300 rpm. At what speed the impeller will be operating, if the power consumed by it is 235 Watts?
