double | mean_pressure |
Laminar pipe flow in two and three dimensions. The channel stretches along the x-axis and has radius radius
. The Reynolds
number is used to scale the pressure properly for a Navier-Stokes problem.

Construct an object for the given channel radius r
and the Reynolds number Re
.
