Transport of the solid helium with imbedded defects in confined domains has been recently reported. Here we used the verified absolute-reaction theory which originates from the quantum chemistry approach together with the boundary perturbation approach to calculate the temperature-dependent viscosity of flowing solid He-4 in the bulk. Both effects of the activation energy and activation volume on the temperature-dependent (shear) viscosity of flowing solid He-4 were illustrated. We found that the temperature-dependent (shear) viscosity which is a ratio of the shear stress and the shear strain rate increases a little as the temperature decreases within the selected temperature regime.
