In the numerator, the mean flow velocity (Manning or Chezy) V.
In the denominator, the relative dynamic or relative Lagrange celerity (gD)0.5.
b.
In the numerator, the relative kinematic or relative Seddon celerity β (V -1). In the denominator, the relative dynamic or relative Lagrange celerity
(gD)0.5.
c. Gravity, friction, pressure gradient, and inertia.
g. A flux is a quantity through an area in a unit of time. Energy is the integral of force in space; momentum is the integral of force in time.
Both energy and momentum apply in the specific case of the hydraulic jump.
e. F = 0.08, in the absence of detailed calculations.
f. About F = 25.
g. Manning's n = 0.05.
h. Manning's n = 1.0
