I understand that when a series diverges, y doesn't approach 0 when x approaches infinity, and converging series do. But what does this say? I just want to understand some applications. …

Oct 25, 2025 · Thread 'How to model converging illumination through object plane (in ZEMAX)' Hello community, I'm designing a projection lens system for a 35mm film projector in Zemax …

Nov 5, 2023 · To determine the focal length of a converging lens graphically, plot the values of 1/di on the y-axis and 1/do on the x-axis. Rearranging the lens formula 1/f = 1/do + 1/di allows …

In particular, take a look at the latest version of his talk on "The life of pi" (and its references!), which includes many of the fast converging algorithms and series used in practice for high …

Jun 9, 2024 · In a compressible flow there is a critical pressure ratio between the upstream and downstream stagnation pressures in order for the flow to become choked, which always …

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 …

Aug 12, 2009 · Hello, I'm a 2nd year student, and I'm trying to get to know COMSOL. I'm starting off by solving simple problems with the incompressible Navier-Stokes model, but I keep having …

Jun 21, 2024 · Choked flow in a converging-diverging nozzle is primarily determined by the stagnation properties before the throat, and the exit pressure influences the Mach number. …

Sep 6, 2007 · now consider a converging diverging section. suppose mach 1 is reached at the throat, at mach 1, section ll not alter the speed of flow, then why would the flow become …

Jul 30, 2014 · The discussion focuses on calculating flow rate in a fluid system involving a pressure source and a converging nozzle, with an outlet to the atmosphere. The user is …
