The familiar logarithmic-velocity wall law is often used in the sense that the mean velocity is a function of the wall shear stress τw, the distance from the wall y, the density of fluid ρ and the viscosity of fluid μ. However, the law should be changed to include the pressure gradient in the case of constant τw as well as in the case of vanishing τw. Based on the wall law applicable to finite and vanishing τw, the slip velocity, which is analytic with respect to the pressure gradient and the friction velocity, is proposed in the logarithmic velocity law and the half-power law. The universal constants in the slip velocity are estimated using experimental data.
