Description We investigate the time scale for the dissipative collapse of a spherical cluster of gas clouds by supplementing the scalar virial equation with an evolution equation for the energy. We find that collapse times are more than doubled even for low filling factors f ~ 10-2 - 10-3, for which support by supernovae, usually considered for galactic structure formation models is ineffective.
