Nominal Pipe Size (NPS) is a North American set of standard sizes for pipes used for high or low pressures and temperatures. [1] " Nominal" refers to pipe in non-specific terms and identifies the diameter of the hole with a non-dimensional number (for example – 2-inch nominal steel pipe" consists of many varieties of steel pipe with the only criterion being a 2.375-inch (60.3 mm) outside ...
Note: Use of this table for estimating bullet masses for historical large-bore rifles is limited, as this table assumes the use of round ball, rather than conical bullets; for example, a typical 4-bore rifle from circa 1880 used a 2,000-grain (4.57 oz; 129.60 g) bullet, or sometimes slightly heavier, rather than using a 4-ounce (110 g) round ...
An underwire size 30 width has a curvature diameter of 3 + 5 ⁄ 6 inches (9.7 cm) and this diameter increases by 1 ⁄ 3 inch (0.85 cm) by size. [101] The table below shows volume calculations for some cups that can be found in a ready-to-wear large size shop.
The VPAM scale as of 2009 runs from 1 to 14, with 1-5 being soft armor, and 6-14 being hard armor. [1] Tested armor must withstand three hits, spaced 120 mm (4.7 inches) apart, of the designated test threat with no more than 25 mm (0.98 inches) of back-face deformation in order to pass.
BL 4 inch naval gun Mk I - VI United Kingdom: 1880s - 1900 102 mm (4.0 in) BL 4 inch Mk VII 50-caliber United Kingdom: World War I - World War II 102 mm (4.0 in) BL 4 inch Mk VIII & XI 40-caliber United Kingdom: World War I - World War II 102 mm (4.0 in) BL 4 inch Mk IX naval gun 45-caliber United Kingdom: World War I - World War II
Example (inch, coarse): For size 7 ⁄ 16 (this is the diameter of the intended screw in fraction form)-14 (this is the number of threads per inch; 14 is considered coarse), 0.437 in × 0.85 = 0.371 in. Therefore, a size 7 ⁄ 16 screw (7 ⁄ 16 ≈ 0.437) with 14 threads per inch (coarse) needs a tap drill with a diameter of about 0.371 inches.
