Abstract: Using stochastic theory of turbulent flow the turbulent flow of power-law fluids in pipes has been studied.Based on the theoretical analysis,a continuous profile function of velocity over flow field u*=A*ln(1+Xξ)-B*(1/(1+Xξ))+C*(1/(1+Xξ)2)+G*(ξ+1c-βξ/β-1/β)+F* and a formula of pressure gradient 2v*{A*[((X+1)2/(2X2))ln(1+X)-1/(2X)-3/4]+B*[1/X-((1+X)/X2)ln(1+X)] +C*[1/X-1/X2ln(1+X)]+F*/2+G*[1/6-1/(2β)+(c-β/β2)+1/β2-1/β3]}-um=0 are proposed.Further,a calculation graph of turbulent pressure gradient for engineering application is given.
