  1. What do convergence and divergence mean? And why do they matter?

    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. NOTE: I'm...

  2. Is there a pressure ratio limit for choked flow through a c-d nozzle ...

    Jun 21, 2024 · The discussion centers on the limits of choked flow through converging-diverging (c-d) nozzles, specifically addressing the effects of diameter and angle in the divergent section. It is …

  3. 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 …

  4. 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 happens at …

  5. Why is my COMSOL solution not converging? - Physics Forums

    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 trouble with …

  6. Why Does Flow Become Supersonic in the Diverging Section of a …

    Sep 6, 2007 · i just started reading about nozzles and turbines in my semester course. i went through converging diverging nozzles. for achieving a supersonic flow, a converging diverging nozzle is used. …

  7. How to Calculate Radii for a Symmetric Converging Lens to Double …

    Feb 16, 2009 · Homework Statement An object is 34.0 cm from a screen. What are the radii of a symmetric converging plastic lens (i.e., two equally curved surfaces)...

  8. Practical Applications of Converging Lenses: Object Positions and Uses

    Jun 1, 2008 · This discussion focuses on the practical applications of converging lenses based on various object positions relative to the focal point (F'). The identified applications include telescopes …

  9. Graphically determining the focal length of a converging lens

    Nov 5, 2023 · This discussion focuses on graphically determining the focal length of a converging lens using the equation 1/f = 1/do + 1/di. The correct approach involves plotting 1/di on the y-axis and …

  10. Converging Lens Problem: Finding Distance from Slide for Real and ...

    Feb 7, 2005 · The discussion centers on solving the Converging Lens Problem involving a lens with a focal length of 2.24 cm and an image distance of 11.4 cm. For a real image, the lens is positioned …
