Coeff of viscosity
Webwhere η0 is the absolute viscosity at atmospheric pressure and λ is the pressure-viscosity coefficient. When calculating the hydrodynamic pressure the reference values of respective parameters were chosen as follows: • Angle to edge of pocket: β = 8.0° • Radius of curvature on rear edge: R = 80 μm • Webrock mechanics. In rock: Stress-strain relationships. The coefficient of viscosity (η) is the ratio of applied stress to the rate of straining (change of strain with time). It is measured …
