Volume was measured in ngogn (equal to 1000 cubic potrzebies), mass in blintz (equal to the mass of 1 ngogn of halva, which is "a form of pie [with] a specific gravity of 3.1416 and a specific heat of .31416"), and time in seven named units (decimal powers of the average earth rotation, equal to 1 "clarke").
At 1 atm pressure, it reaches its maximum density of 999.972 kg/m 3 (62.4262 lb/cu ft) at 3.98 °C (39.16 °F). [ 54 ] [ 55 ] Below that temperature, but above the freezing point of 0 °C (32 °F), it expands becoming less dense until it reaches freezing point, reaching a density in its liquid phase of 999.8 kg/m 3 (62.4155 lb/cu ft).
[203] [219] The columns consist of 2-to-3-inch-thick (5.1 to 7.6 cm) concrete shells surrounding a hollow shaft, [203] [220] the concrete shells have steel mesh cores for added strength. [80] [218] The columns are made of Portland cement and can carry loads of up to 7,000 pounds per square inch (48,000 kPa), higher than what Wright had specified.
The 1301 consisted of one (for Model 1) or two (for model 2) modules, each containing 25 platters, each platter about 1 ⁄ 8-inch (3.2 mm) thick and 24 inches (610 mm) in diameter. [32] While the earlier IBM disk drives used only two read/write heads per arm, the 1301 used an array of 48 [ l ] heads (comb), each array moving horizontally as a ...
So the range of the 5 pounds per square inch (34 kPa) overpressure damage expected from a detonated 12 kiloton weapon with a height of burst at 1,968 feet (600 m) would be expected to be 0.98 miles (1.58 km), whereas a 20 kiloton weapon would have the same range extend to 1.12 miles (1.80 km), a difference of only 0.14 miles (0.23 km).
The separation buildings were massive windowless concrete structures, 800 feet (240 m) long, 80 feet (24 m) high and 65 feet (20 m) wide, with concrete walls 3 to 5 feet (0.91 to 1.52 m) thick. Inside the buildings were canyons and galleries where a series of chemical processing steps separated the small amount of plutonium from the remaining ...
The base was measured to be about 230.3 metres (755.6 ft) square, giving a volume of roughly 2.6 million cubic metres (92 million cubic feet), which includes an internal hillock. [6] The dimensions of the pyramid were 280 royal cubits (146.7 m; 481.4 ft) high, a base length of 440 cubits (230.6 m; 756.4 ft), with a seked of 5 + 1 / 2 ...
