The distributions of flow rate and mixig ratio are studied for a spray generated by two impinging jets which are generally used for bipropellant liquid rocket systems using hypergol. The propellant system was simulated by the water model in the previous report (1st report), in which two jets had same sizes and same injection pressure drop. The water model was adopted again in teh present report using two jets with different sizes and injection pressure drop. When two jets impinge together with different injection pressure drop from two orifices of same sizes, the total mixing efficiency of teh spray decreases as the difference of the pressure increases. When the injection pressure drop is same and the dimensions of orifices are different, the total mixing efficiency varies with the increase of the difference of the diameters, but the variation is small. When two jets were composed from immiscible liquids, the state of mixing is basically same with that of miscible liquids
