Once you have defined the boundary conditions, start trial sketching of flow lines and equipotentials, following the rules in step 2 above, and being sure that the flow lines and equipotentials always intersect at right angles. " These lines are called isobars because they connect areas where the air pressure is the same ("iso-" meaning equal and "-bar" meaning pressure). 1) BA (h ολ = H) is the first equipotential line. As presented in the previous sub sections, a set of parallel flow lines encompasses a flow tube. MindManager, an industry-leading swim lane diagram software, allows you to create complex, detailed swim lane diagrams with ease.

Choropleth map advantages include: Conveys an idea of geographic distribution with minimal effort. The flow from the manifold is then transferred by a gathering line to a pre-processing stage or to a transportation facility or vessel. Lean practitioners use the process and the. Also remember that winds flow from high to low areas, so this gives meteorologists a chance to predict local wind patterns as well. This map is stationary with time i. the combination of the cylindrical and conic projection. In value stream mapping, the material flow is usually highly linear. Winds occur on a range of scales, from thunderstorm flows lasting tens of minutes, to local breezes generated by heating of land surfaces and lasting a few hours, to global. It’s any data used in the flowchart. 500-mb vorticity is also termed vertical vorticity (the spin is in relation to a vertical axis). Choropleth Map.
