Machinery
Power was provided by Parsons high pressure steam turbines, driving four shafts. There were eighteen boilers, manufactured by Babcock and Wilcox. The boiler working pressure was 235-240 pounds per square inch. Each boiler was heated by three single-orifice burners of standard Admiralty type; each burner could consume 300 lb (140 kg) of oil per hour. Maximum claimed horse power was 25,000. Up to 2,900 tons of coal and 900 tons of oil could be carried as fuel; a full load gave a radius of 6,680 nautical miles (12,370 km) at 10 knots (19 km/h) or 4,050 nautical miles (7,500 km) at 18.5 knots (34.3 km/h). Trial performance figures, which were normally run under best possible conditions and would not have been normally attainable in service, show a maximum speed of 22.6 knots (41.9 km/h), 8-hour speed at full power of 21.5 knots (39.8 km/h), and 30-hour speed at 18.000 horsepower (13.423 kW) of 19.6 knots (36.3 km/h).

Famous quotes containing the word machinery:
“Man will never be enslaved by machinery if the man tending the machine be paid enough.”
—Karel Capek (1890–1938)
“There has been something crude and heartless and unfeeling in our haste to succeed and be great. Our thought has been “Let every man look out for himself, let every generation look out for itself,” while we reared giant machinery which made it impossible that any but those who stood at the levers of control should have any chance to look out for themselves.”
—Woodrow Wilson (1856–1924)
“In the arts of life man invents nothing; but in the arts of death he outdoes Nature herself, and produces by chemistry and machinery all the slaughter of plague, pestilence, and famine.”
—George Bernard Shaw (1856–1950)
