The meaning of jet engine performance has been phrased as 'the end product that a jet engine company sells' [1] and, as such, criteria include thrust and fuel consumption, life, weight, emissions, diameter and cost. Performance criteria reflect the level of technology used in the design of an engine and the technology has been advancing ...
The team found that the railroad's goals could be achieved by enlarging the Challenger firebox to about 235 by 96 inches (5.97 m × 2.44 m) (about 150 sq ft or 14 m 2), increasing boiler pressure to 300 psi (2.1 MPa), adding four driving wheels, and reducing the size of the driving wheels from 69 to 68 in (1,753 to 1,727 mm).

The introduction of the 4-6-2 design in 1901 has been described as "a veritable milestone in locomotive progress". [3] On many railways worldwide, Pacific steam locomotives provided the motive power for express passenger trains throughout much of the early to mid-20th century, before either being superseded by larger types in the late 1940s and 1950s, or replaced by electric or diesel-electric ...
IEEE 802.11a/g/n, operating in the 2.4 and 5 GHz bands, specifies per-stream airside data rates ranging from 6 to 54 Mbit/s. If both devices can use "HT mode" (added with 802.11n ), the top 20 MHz per-stream rate is increased to 72.2 Mbit/s, with the option of data rates between 13.5 and 150 Mbit/s using a 40 MHz channel.

Evolved from. 2-6-2+2-6-2. Under the Whyte notation for the classification of steam locomotives by wheel arrangement, a 4-6-2+2-6-4 is a Garratt or Union Garratt articulated locomotive using a pair of 4-6-2 engine units back to back, with the boiler and cab suspended between them. The 4-6-2 wheel arrangement of each engine unit has four leading ...
