New results are presented for the excess pressure drop in the entrance flow of inelastic materials. These predictions demonstrate how shear thinning effects promote higher pressure losses in the entrance geometry. A flow reversibility result, identical to the slow flow reversibility principle for Newtonian materials, is established for the creeping flow of an inelastic fluid.
