An agitator shaft must withstand combined torsional and bending stresses without deflecting excessively or hitting its critical resonant frequency. Torque Calculation Tqcap T sub q ) is derived directly from the impeller shaft power:

To calculate the final motor size, electrical and mechanical losses must be accounted for using system efficiencies:
