The all characteristics of the swirl nozzle are affected by the viscosity of liquid, but the effect upon the discharge coefficient among these is considerably complicated. In this paper, the effects of the surface tension and the viscosity on the discharge coefficient were investigated. The discharge coefficients are fairly arranged by introducing a Reynolds' number R_e of the swirl chamber, and in the range of R_e=1 600-2 800,all swirl injection nozzles have a transition from the laminar flow to the turbulent. The changes of discharge coefficients by the transition are rather gradual, including the extreme case of no change. A general empirical formula of discharge coefficient was made from the results.
