| TO HS{Lord Ernest Hives - Chair}/RM.{William Robotham - Chief Engineer} FROM R.{Sir Henry Royce} ORIGINAL R2/M22.7.26. re. SCAVENGER PUMPS. Is it possible that these pumps could be driven at a slower speed. This idea is taken from the fact that we generally have more oil circulating than is required, so that if we could reduce the speed of the pump it would probably be more economical from a heat point of view, than reducing their size. Apparently a wide pump having wheels of small diameter might be found more efficient than a narrow pump of large diameter at least for scavenger work. 9-30 26/7 R.{Sir Henry Royce} | ||
