It was originally defined as the rate of heat transfer that results in the freezing or melting of 1 short ton (2,000 lb; 907 kg) of pure ice at 0 °C (32 °F) in 24 hours. [1] [2] The modern definition is exactly 12,000 Btu IT /h (3.516853 kW). Air-conditioning and refrigeration equipment capacity in the U.S. is often specified in "tons" (of ...
Sizes were rationalized, with 1 ⁄ 4 and 3 ⁄ 4-ton 4x4s and 2 + 1 ⁄ 2, 5, and 10-ton 6x6s. Trucks were military standard designs, 6x6 trucks used common cabs and similar fender and hood styles. Trucks were military standard designs, 6x6 trucks used common cabs and similar fender and hood styles.
The TravelMate 2420 was a Centrino based laptop computer, featuring either a Celeron M or a Pentium M processor at 1.7 GHz, depending on the region where it was to be distributed. [6] As of April 2007, this model was discontinued by Acer Corp in the USA and Mexico.
Cooling capacity is the measure of a cooling system's ability to remove heat. [1] It is equivalent to the heat supplied to the evaporator/boiler part of the refrigeration cycle and may be called the "rate of refrigeration" or "refrigeration capacity".
The G-506 trucks, 1 + 1 ⁄ 2-ton, 4x4, produced as the Chevrolet G7100 (and originally G4100) models, were a series of (light) medium four wheel drive trucks used by the United States Army and its allies during and after World War II. This series came in standard cargo, as well as many specialist type bodies.
For non-sequential numbers, like M1 Abrams, see bottom of list. M1 combat car, also known as the M1 light tank; M1 light motorcycle; M2 light tank, .5" MG or 37 mm gun, 11-ton
The usual compression, cooling and expansion seen in any refrigeration cycle is accomplished in the ACM by a centrifugal compressor, two air-to-air heat exchangers and an expansion turbine. Bleed air from the engines, an auxiliary power unit, or a ground source, which can be in excess of 150 °C and at a pressure of perhaps 32 psi (220 kPa ...
The physical size of the gearbox was 17 inches (430 mm) in diameter, [2] or no more than half the gearbox size of the PW-Allison 578-DX propfan demonstrator engine that Pratt & Whitney worked jointly on with Allison in the 1980s. The gearbox consisted of 40 components, weighed 500 lb (230 kg), and shared a 3-U.S.-gallon (11-liter) oil tank with ...
