What do convergence and divergence mean? And why do they …
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. …
Series that converge to $\pi$ quickly - Mathematics Stack Exchange
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 …
Why is my COMSOL solution not converging? - Physics Forums

Graphically determining the focal length of a converging lens
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 …
How to determine when compressible flow is choked?
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 …
Is it possible to have a Mach number greater than 1 at the throat?
Mar 5, 2012 · The discussion centers on whether a Mach number greater than 1 can occur at the throat of a converging-diverging nozzle. Initially, it is asserted that the Mach number at the …
Why Does Flow Become Supersonic in the Diverging Section of a …
Sep 6, 2007 · While a converging section only supports subsonic flow, the diverging section can accelerate the flow beyond the speed of sound due to compressible flow dynamics. The …
Is there a pressure ratio limit for choked flow through a c-d nozzle ...
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. …
