N2 - By use of the recently proposed model of the dynamics of a macromolecule in transient extensional flows, the effective viscosity increase in turbulence due to unraveling macromolecules is calculated, and a relation between this viscosity increase and a drag reduction parameter (the slope increment) is derived. The predictions of the theory are in good agreement with experiment.
