A cylindrical tank (1.2 m diameter) is filled with water to an operating level equal to the tank diameter. The tank is equipped with four equally spaced baffles whose width is one tenth of the tank diameter. The tank is agitated with a 0.36 m diameter flat six bladed disk turbine. The impeller rotational speed is 2.8 rps. The air enters through an open-ended tube situated below the impeller and its volumetric flow rate 0.00416 m /s at 1.08 atm and 25 °C. Calculate the power requirement for the agitation. The relation between the gassed and ungassed power requirement is given by D. 교 196(을) 0.115 4.38 D. 2 D.n 2 Dn T. log 10 ) = - 192 () (4 nD g I Where y = kinematic viscosity D, = Impeller diameter D, = Tank diameter n = Impeller speed Q = Volumetric gas flow rate A cylindrical tank (1.2 m diameter) is filled with water to an operating level equal to the tank diameter.
