Abstract The continuous non isometric time space grey model GM(1,1) was applied to the study on the friction coefficient and the reynolds number's relation.A mathematical model of continuous prediction was set up and compared with the built model.The results are in good agreement with the measured ones.According to inspection,the model accuracy of every built model is grade one.The model is adaptable to predict the frication coefficient of the pipe system which has certain degree of rough.
