A butler's sink is a rectangular ceramic sink with a rounded rim which is set into a work surface. [4] There are generally two kinds of butler's sinks: the London sink and the Belfast sink. [ 4 ] In 2006, both types of sinks usually were 61 centimetres (24 in) across and 46 centimetres (18 in) front-to-back, with a depth of 22.5 centimetres (8. ...
A signal-flow graph or signal-flowgraph (SFG), invented by Claude Shannon, [1] but often called a Mason graph after Samuel Jefferson Mason who coined the term, [2] is a specialized flow graph, a directed graph in which nodes represent system variables, and branches (edges, arcs, or arrows) represent functional connections between pairs of nodes.
Thermodynamic heat pump cycles or refrigeration cycles are the conceptual and mathematical models for heat pump, air conditioning and refrigeration systems. [1] A heat pump is a mechanical system that transmits heat from one location (the "source") at a certain temperature to another location (the "sink" or "heat sink") at a higher temperature. [2]

Stability diagram classifying Poincaré maps of linear autonomous system ′ =, as stable or unstable according to their features. Stability generally increases to the left of the diagram. [ 1 ] Some sink, source or node are equilibrium points .
Furthermore, the convective heat flux can be determined via the definition of the heat transfer coefficient h, ″ = (), where is the temperature of the surroundings. The differential convective heat flux can then be determined from the perimeter of the fin cross-section P,
Carnot engine diagram (modern) - where an amount of heat Q H flows from a high temperature T H furnace through the fluid of the "working body" (working substance) and the remaining heat Q C flows into the cold sink T C, thus forcing the working substance to do mechanical work W on the surroundings, via cycles of contractions and expansions.
SysML's diagrams express system engineering concepts better due to the removal of UML's software-centric restrictions and adds two new diagram types, requirement and parametric diagrams. The former can be used for requirements engineering; the latter can be used for performance analysis and quantitative analysis. Consequent to these ...
