It depends on what your fuel air ratio is. The NACA reports were ONLY interested in the compressor effeciency of the turbine, other effects of the water were irrelevant on a jet engine.
If your fuel air ratio was 12.5:1 , 3% or air would be 37.5% of fuel, if you were running a 10:1 fuel air ratio that same 3% of air mass would be about 30% of fuel. In the case of the war birds they typically ran 50% of fuel for their injection systems. Larry
