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:
“We saw the machinery where murderers are now executed. Seven have been executed. The plan is better than the old one. It is quietly done. Only a few, at the most about thirty or forty, can witness [an execution]. It excites nobody outside of the list permitted to attend. I think the time for capital punishment has passed. I would abolish it. But while it lasts this is the best mode.”
—Rutherford Birchard Hayes (1822–1893)
“A fine-looking mill, but no machinery inside.”
—Hawaiian saying no. 1702, ‘lelo No’Eau, collected, translated, and annotated by Mary Kawena Pukui, Bishop Museum Press, Hawaii (1983)
“There is no country in the world where machinery is so lovely as in America.”
—Oscar Wilde (1854–1900)
