    Simplified temperature/pressure phase change diagram for water. The pressure on a pressure-temperature diagram (such as the water phase diagram shown above) is the partial pressure of the substance in question.

  4. 2-10-2 - Wikipedia

    en.wikipedia.org/wiki/2-10-2

    The 2-10-2 's inherent problem was the low speed restriction on the type, which was about 35 mph (56 km/h). Further, the 2-10-2 had other inherent restrictions. The massive cylinders that were required on locomotives in the United States for high tractive effort had the result that no reasonably sized valves could admit and exhaust steam at a ...

    All 2-10-10-2 locomotives have been articulated locomotives of the Mallet type. This wheel arrangement was rare. Only two classes of 2-10-10-2 locomotives have been built: the Atchison, Topeka and Santa Fe Railway's 3000 class, and the Virginian Railway's class AE. The 3000 class performed poorly, so the railroad returned them to their original ...

    The 2-10-0 arrangement was a very popular one in Germany. The first were built by the individual state railways from 1915 to 1918, and these later became the DRG BR58. The DRG then produced a number of standard classes of 2-10-0s: the heavy 3-cylinder BR44 (1753 built), the two-cylinder version BR43 (35 built), and the lightweight BR50 (3164
