  In the preceding paper (Efroimsky 2017), we derived an expression for the
tidal dissipation rate in a homogeneous near-spherical Maxwell body librating
in longitude. Now, by equating this expression to the outgoing energy flux due
to the vapour plumes, we estimate the mean tidal viscosity of Enceladus, under
the assumption that the Enceladean mantle behaviour is Maxwell. This method
yields a value of $\,0.24\times 10^{14}\;\mbox{Pa~s}\,$ for the mean tidal
viscosity, which is very close to the viscosity of ice near the melting point.
