抄録

Values of aerated power required at upper and lower stages of a dual impeller under loading state in stirred vessels were measured with a unique method. The following points. were revealed.<BR>1) The power of the lower stage in most dual impellers and the power of the upper stage for the impeller of largest diameter in this work were equal to that of a single impeller operating in the same condition. 2) The power of the upper stage was smaller than that expected for an unaerated impeller in a fluid of density equal to that of the gas-liquid mixture.
