WebbJan 1997. Klaus Böttcher. Kiyoshi Shimamura. Tsuguo Fukuda. The viscosity of La3Ga5SiO14 melt was measured by a fixed-crucible rotor technique in the range … WebbAt ý = ý c the zero shear rate viscosity η 0 has to be equal to the power law viscosity: η 0 = k m M α = Φ ý c n-1 . or. ý c = (Φ / k m M α) 1/(n-1) The parameter α is the inverse of n: n = α-1. This is not surprising since n describes the disentanglement (shear-thinning) an α the entanglement state at zero shear rate. progressive sport 490 shocks
