This is a simple script that computes normal flow for pipes and rectangular channels. I wrote this on JavaScript at some point when I needed to determine flow capacities for pipes.

Shape:
Diameter, d (ft)
Roughness, n
Slope, s
Depth, y (ft)
Units
Area, A (ft2)
Perimeter, P (ft)
Radius, R (ft)
Velocity, V (fps)
Flow, Q (cfs)
