Supernova-driven galactic wind and metal enrichment in spheroidal star systems are considered within the general framework of the closed one-zone-model approach. Three issues are addressed: i) protogalaxy binding energy, ii) non-uniform gas density distribution, iii) presence of dark matter. Models of a galaxy with a mass of 1010 M are discussed for illustrative purposes.
