| HS.{Lord Ernest Hives - Chair} FROM R.{Sir Henry Royce} Copy to WOR.{Arthur Wormald - General Works Manager} [crossed out] BY.{R.W. Bailey - Chief Engineer} [crossed out] E.{Mr Elliott - Chief Engineer} [crossed out] SS.{S. Smith} & G.4. INDUCTION PIPE. X7070 X5070 In examining the distribution we cannot help thinking that there is sure to be a difference with different speeds - i.e. suppose the mixture was rich at the ends at high speeds it might be rich at the middle at low speeds. Such a trouble might be very difficult to cater for. In the case of G.4. it should be quite easy to heat the jacket to any reasonable temperature by the use of steam. After testing it hydraulically to see what it would carry we might try steam pressure up to reasonable safety. The air temperature under the bonnet will sure to be in the neighbourhood of 50oC. This should be examined. R.{Sir Henry Royce} | ||
