SFR for three values of L_i, the injection length of turbulence, and several values of n₀, the mean density, as a function of the Mach number. Solid lines represent the model using the Castaing-Hopkins PDF and dot-dashed ones used the log-normal PDF. For all curves η_d = 0.5. The star markers correspond to the Mach number which results from the mechanical equilibrium within a self-gravitating gas rich galactic disk as stated by Eq. (59).
