    Collects steam at the top of the boiler (well above the water level) so that it can be fed to the engine via the main steam pipe, or dry pipe, and the regulator/throttle valve. [2] [5] [6]: 211–212 [3]: 26 Air pump / Air compressor Westinghouse pump (US+) Powered by steam, it compresses air for operating the train air brake system.

    While pipe sizes in Australia are inch-based, they are classified by outside rather than inside diameter (e.g., a nominal 3 ⁄ 4 inch copper pipe in Australia has measured diameters of 0.750 inches outside and 0.638 inches inside, whereas a nominal 3 ⁄ 4 inch copper pipe in the U.S. and Canada has measured diameters of 0.875 inch outside and ...

    en.wikipedia.org/wiki/Nominal_Pipe_Size

    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 colours dark and light green represent wet and dry steam respectively. The colours orange and yellow represent hot and cooler exhaust gas respectively. In the diagram, three small-diameter orange/yellow empty firetubes are indicated to the bottom, with two larger diameter orange/yellow firetubes to the top that contain the superheater elements.

    where is the density of the fluid, is the average velocity in the pipe, is the friction factor from the Moody chart, is the length of the pipe and is the pipe diameter. The chart plots Darcy–Weisbach friction factor against Reynolds number Re for a variety of relative roughnesses, the ratio of the mean height of roughness of the pipe to the ...

  8. Flare fitting - Wikipedia

    en.wikipedia.org/wiki/Flare_fitting

    Copper and its alloys, mild steel, and in some cases small diameter stainless steel pipes are most commonly reamed with hand tools. [ 15 ] Copper is perfectly machinable, a quality tool successfully performs wall deformation, the surface remains smooth, the wall thickness is almost the same, and the material retains a homogeneous structure.

  9. Axial-flow pump - Wikipedia

    en.wikipedia.org/wiki/Axial-flow_pump

    An axial-flow pump for industrial use. An axial-flow pump, or AFP, is a common type of pump that essentially consists of a propeller (an axial impeller) in a pipe.The propeller can be driven directly by a sealed motor in the pipe or by electric motor or petrol/diesel engines mounted to the pipe from the outside or by a right-angle drive shaft that pierces the pipe.
