摘要：
This paper proposes a new method to calculate the volumetric efficiency and hydraulic efficiency of centrifugal pumps based on the principle of energy balance. Two efficiencies are calculated by means of a low specific speed centrifugal pump handling media with different viscosities at best efficiency points and are compared with those of two existing methods. The results manifest that the definition of two efficiencies in the present paper is more precisive and sensitive to the change of liquid viscosity.
