Notes. (1) Total kinetic energy provided by infalling gas, calculated from Eq. (3) using $\dot{M} = \dot{M}_{\rm SF}$ and $v_{\rm in} = v_{\rm rot}$. (2) Total dissipation rate of turbulent kinetic energy $\vert\dot{E}_{\rm decay,HD}\vert$ obtained from integrating Eq. (2) over the entire galaxy using $L_{\rm d} $ derived from vertical hydrostatic equilibrium. (3) Minimum efficiency $\epsilon_{\rm HD} = \vert\dot{E}_{\rm decay,HD}\vert/\dot{E}_{\rm in}$ required for the conversion of infall motion into turbulent energy in the disk. (4) Integrated turbulent decay rate $\vert\dot{E}_{\rm decay,pot}\vert$ based on the potential method. (5) Corresponding minimum efficiency $\epsilon _{\rm pot}$. (6) Integrated turbulent decay rate $\vert\dot{E}_{\rm decay,R_{25}}\vert$ based on the assumption that the outer scale of the turbulent velocity field is equal to the size of the disk $L_{\rm d} \sim2~R_{25}$. (7) The corresponding required minimum efficiency $\epsilon _{\rm R_{25}}$ for accretion driven turbulence to work. (8) Total kinetic energy $E_{\rm kin}$ integrated over the whole galaxy. (9) Fraction of total kinetic energy outside the optical radius R25. (10) Fraction of turbulent energy decay rate outside of R25 using the disk vertical scale height from hydrostatic balance. The total rate is given in Col. (2). (11) Corresponding required accretion efficiency to drive the turbulence in the outer disk for R > R25. Compare to the total galactic value given in Col. (3). The outer disk value is typically a factor of 5 lower.
