| c/o H.M.A. R.100 Cardington Bedford 21.1.30 Dear Rm{William Robotham - Chief Engineer}, Many thanks for your kindly given information with regard to E.G. I did not mean to convey we had any intention of using the stuff in its natural state, as of course trouble was to be expected from its hygroscopic characteristics. I haven't the S.A.E. Journal before me, but I seem to remember that quite a low percentage of E.G. mixed with water will raise the boiling point of the mixture appreciably. (At a guess, 30% to 110°C, 50% to 130°C) | ||
