Hello,
Let's say I have an ideal cylindrical pool (rigid, vertical walls) of diameter d, with water of depth h. Take the ratio of d:h to be around 5:1 - 10:1. If I press down on the surface with a plunger of width w, I cause a standing wave resembling a single-node Bessel function, like a vibrating membrane with non-fixed edges. Taking into account the viscosity and surface tension, what are the expressions for (and how are they obtained)

- wave decay time
- wave amplitude
