We consider a generalised Webster’s equation for describing wave propagation in curved
tubular structures such as variable diameter acoustic wave guides. Webster’s equation in
generalised form has been rigorously derived in a previous article starting from the wave
equation, and it approximates cross-sectional averages of the propagating wave. Here,
the approximation error is estimated by an a posteriori technique.
