The 4 ft 6 in (1,372 mm) track gauge, also called the Scotch gauge, was adopted by early 19th century railways mainly in the Lanarkshire area of Scotland. It differed from the gauge of 4 ft 8 in ( 1,422 mm ) that was used on some early lines in England .
Until early in the 20th century, it was the unit used to measure the depth of mines (mineral extraction) in the United Kingdom. [30] Miners also use it as a unit of area equal to 6 feet square (3.34 m 2) in the plane of a vein. [2] In Britain, it can mean the quantity of wood in a pile of any length measuring 6 feet (1.8 m) square in cross ...
Some railways, primarily in the northeast, used standard gauge of 4 ft 8 + 1 ⁄ 2 in (1,435 mm); others used gauges ranging from 2 ft (610 mm) to 6 ft (1,829 mm). As a general rule, southern railroads were built to one or another broad gauge, mostly 5 ft ( 1,524 mm ), while northern railroads that were not standard-gauge tended to be narrow-gauge.
The Cutthroat flume is a class of flow measurement flume developed during 1966/1967 that is used to measure the flow of surface waters, sewage flows, and industrial discharges. Like other flumes , the Cutthroat flume is a fixed hydraulic structure .
Using the Parshall flume flow equations and Tables 1-3, determine the flow type (free flow or submerged flow) and discharge for a 36-inch flume with an upstream depth, Ha of 1.5 ft and a downstream depth, H b of 1.4 ft. For reference of locations H a and H b, refer to Figure 1.
Earlier built 4 ft 8 + 1 ⁄ 2 in (1,435 mm) and broad gauge railways were soon converted to the narrower gauge. The Cape Colony adopted the 3 ft 6 in gauge. [ 4 ] [ 5 ] After conducting several studies in southern Europe, the Molteno Government selected the gauge as being the most economically suited for traversing steep mountain ranges. [ 6 ]
