The high-pressure liquid enters a boiler, where it is heated at constant pressure by an external heat source to become a dry saturated vapour. The input energy required can be easily calculated graphically, using an enthalpy–entropy chart (h–s chart, or Mollier diagram), or numerically, using steam tables or software. Process 3–4
Popularly used for the small scale live steam. No.1: 1:32: 45 mm (1.772 in) Popularly used for the small scale live steam. Corresponds to NEM 1 or NMRA No. 1. No.3: 1:22.6: 2 + 1 ⁄ 2 in (64 mm) The smallest scale able to pull real passengers. Was one of the first popular live steam gauges, developed in England in the early 1900s.
Sankey diagrams are named after Irish Captain Matthew Henry Phineas Riall Sankey, who used this type of diagram in 1898 in a classic figure [3] (see diagram) showing the energy efficiency of a steam engine. The original charts in black and white displayed just one type of flow (e.g. steam); using colors for different types of flows lets the ...
The following sizing methodology is based on the assumption that those flow rates are known. Use a vertical pressure vessel with a length–diameter ratio of about 3 to 4, and size the vessel to provide about 5 minutes of liquid inventory between the normal liquid level and the bottom of the vessel (with the normal liquid level being somewhat ...
