Abstract

The pressure losses prior to entry into a nozzle are determined in the flow of a viscoelastic medium in broad ranges of the viscosity and the discharge. A generalized dependence of the entrance pressure losses on the rate of shear is obtained in dimensionless form. An empirical equation is proposed for the computation of entrance pressure losses.
