11.3 Determine and plot the relation between water velocity and depth over the range of V = 0 1m s to 10m s for Froude numbers of 0.5 (subcritical), 1.0 (critical), and 2 (supercritical). Explain how the flow can be subcritical, critical, or supercritical for

(a) the same velocity and

(b) the same depth.
