Abstract：Slip factor of centrifugal pumps is very important to theoretical head calculation.The present research situations on slip factor of centrifugal pumps,definition and characters of slip factor are(reviewed).Based on the practical efficiency calculation of many excellent centrifugal pumps,the Stodola,Stechkin,and Weisner slip coefficient formulas are compared.The standard of comparison is experiment efficiency.Compared with experiment efficiency,the research indicates that Weisner formula(n_s<65) and Stechkin formula(n_s>65) are more accurate for centrifugal pumps and that the Stodola formula is not suitable for centrifugal pumps.centrifugal pump;slip factor;precision;theory head;characteristics prediction
