| Mr. Wheeler. from Rm{William Robotham - Chief Engineer}/GB. Rm{William Robotham - Chief Engineer}/GB.1/ML.5.8.40. LOWER HALF RIG TEST. Results of capacity tests made today on lower half on Clan rig, were as follows :- | Pump Speed. r.p.m. | Time for 1.5 galls. seconds. | Average Flow. pints/hr. | Min: permissable Flow. pints/hr. | |--------------------|------------------------------|-------------------------|------------------------------------| | 370 | 80: 82-1/5 | 532 | 520 | | 1590 | 16: 16.8 | 2630 | 2600 | | 2140 | 11-1/5 : 12-2/5 - 12. | 3630 | 3500 | During the above tests the corrected temperature was 76 deg. C. The Auxiliary oil pressure was 9 lbs/sq. ins. at 1590 r.p.m. The temperature for the "cold oil" tests was 28 deg. C. Rm{William Robotham - Chief Engineer}/GB. | ||
