In the imperial measurement systems, "pitch" is usually expressed with the rise first and run second (in the US, run is held to number 12; [1] e.g., 3:12, 4:12, 5:12). In metric systems either the angle in degrees or rise per unit of run, expressed as a '1 in _' slope (where a '1 in 1' equals 45°) is used.
Grade indicator near Bellville, Western Cape, South Africa, showing 1:150 and 1:88 grades. Ruling gradients limit the load that a locomotive can haul, including the weight of the locomotive itself. Gradients are expressed as a ratio of vertical rise to horizontal distance; for example, a 1% gradient (1 in 100) means the track rises 1 vertical ...
As part of the project, four-inch (10 cm) perforated tiles were installed at 12.5-foot (3.8 m) centers across the entire field in order to improve drainage. In 2014, the Royals started placing a "W" on the Hall of Fame wall for every home win, similar to the Chicago Cubs hoisting a white flag with a blue "W" at Wrigley Field for every Cub home win.
If the interior of a home is at 20 °C and the roof cavity is at 10 °C then the temperature difference is 10 °C (or 10 K). Assuming a ceiling insulated to RSI 2.0 (R = 2 m 2 ⋅K/W), energy will be lost at a rate of 10 K / (2 K⋅m 2 /W) = 5 watts for every square meter (W/m 2) of ceiling. The RSI-value used here is for the actual insulating ...
These are made of cinder concrete, topped with lightweight cinder-concrete tiles. [238] Each roof is composed of slabs measuring 40 + 2 ⁄ 3 feet (12.4 m) wide. [314] The auditorium roof's eaves extend 5 feet (1.5 m) outward from the facade's columns, [324] overhanging the adjacent lawns and paths. [306]

[3] In Barranco de Valtamujo there remains of a Roman bridge, that possibly connect to another along the Ardila River, and near the port of Castelo.
