Identifying Converging and Diverging Lenses: Explaining with Principal ...
Feb 1, 2005 · To determine whether a lens is converging or diverging, analyze the behavior of the principal rays after they pass through the lens. A convex lens will cause rays to converge at a point …
How to determine when compressible flow is choked?
Jun 9, 2024 · In compressible flow, choking occurs at the minimum cross-sectional area, or throat, when the upstream to downstream pressure ratio is 0.528 for air. The introduction of a diverging section …
Why Does Flow Become Supersonic in the Diverging Section of a Nozzle?
