| R.R. 493A (50 H) (D.D. 31, 12-6-25) J.H.D. EXPERIMENTAL REPORT. -3- Expl. No. REF: HS{Lord Ernest Hives - Chair}/ACL/LG7.12.25 noticed to be proportionally greater at the high speeds than at the low. From the curves given here it will be seen that the consumptions and flows, both for seven and three bearing feeds, are greater than the corresponding figures.
