The Pratt & Whitney R-4360 Wasp Major is an American 28-cylinder four-row radial piston aircraft engine designed and built during World War II.At 4,362.5 cu in (71.5 L), it is the largest-displacement aviation piston engine to be mass-produced in the United States, and at 4,300 hp (3,200 kW) the most powerful.
It was 1.5 inches longer, 2.6 inches wider, and 0.84 inches shorter than the 283 "small-block". ... The ZL1 engine also featured a lightweight aluminum water pump, a ...
Although the U.S. light tanks had proven effective in jungle warfare, by late 1943, U.S. Marine Corps tank battalions were transitioning from their M3/M5 light tanks to M4 medium tanks, mostly for the much greater high-explosive blast effect of the M4's 75mm gun, which fired a much larger shell with a heavier explosive payload.
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 ...
Following the turbo domination, forced induction was allowed for two seasons before its eventual ban. The FIA regulations limited boost pressure, to 4 bar in qualifying in 1987 for 1.5 L turbo; and allowed a larger 3.5 L formula. Fuel tank sizes were further reduced in size to 150 litres for turbo cars to limit the amount of boost used in a race.
The length and diameter of a water meter's tube are standardized to ensure compatibility with plumbing systems and adherence to regulatory requirements. Water meter diameters are typically measured in nominal pipe sizes (NPS) and are commonly available in sizes ranging from 15 mm (½ inch) to 300 mm (12 inches) or larger for industrial ...
The .408 Cheyenne Tactical is based on the .400 Taylor Magnum, which itself is based on a modified .505 Gibbs, necked down to 0.408 inches (10.36 mm). The .505 Gibbs is an old English big-game cartridge that was designed to accommodate 39,160 psi (270 MPa) pressure.
Where p is the pressure, T is the temperature, R the ideal gas constant, and V m the molar volume. a and b are parameters that are determined empirically for each gas, but are sometimes estimated from their critical temperature (T c) and critical pressure (p c) using these relations:
