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 ...
The low-pressure oxidizer turbopump (LPOTP) is an axial-flow pump which operates at approximately 5,150 rpm driven by a six-stage turbine powered by high-pressure liquid oxygen from the high-pressure oxidizer turbopump (HPOTP). It boosts the liquid oxygen's pressure from 0.7 to 2.9 MPa (100 to 420 psi), with the flow from the LPOTP then being ...
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 ...
Fuel consumption of the M4A2 was lower than that of other Shermans: 1.1 mpg (214 liters per 100 km) on the highway, and 0.5 miles per gallon (470 liters per 100 km) on off-road. On average, tanks consumed 0.81 quarts (0.76 liters) of oil per engine hour. The tests ended on 11 May. By that time, the M4A2 had covered 22,126 miles, running 2,424 ...
medium-bore refers to calibers with a diameter of 0.33 inches (8.4 mm) to 0.39 inches (9.9 mm) large-bore refers to calibers with a diameter of 0.40 inches (10 mm) or larger There is much variance in the use of the term "small-bore", which over the years has changed considerably, with anything under 0.577 inches (14.7 mm) considered "small-bore ...
[54] [87] The system was designed for about 6 pints (2.8 liters) of water per shower, [88] the water being drawn from the personal hygiene water tank. [54] The use of both the liquid soap and water was carefully planned out, with enough soap and warm water for one shower per week per person.
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.
Aquarium heaters combine a heating element with a thermostat, allowing the aquarist to regulate water temperature at a level above that of the surrounding air, whereas coolers and chillers (refrigeration devices) are for use anywhere, such as cold water aquaria, where the ambient room temperature is above the desired tank temperature.
