Choose the correct answer
A
q = k × h × (N_d/N_f)
B
q = k × h × (N_f/N_d)
C
q = k × N_f × N_d
D
q = k × h / (N_f × N_d)
Correct Answer
B. q = k × h × (N_f/N_d)

q = k × h × N_f/N_d, where k = permeability, h = total head loss, N_f = number of flow channels, N_d = number of equipotential drops (head drops). The ratio N_f/N_d ≈ shape factor of the flow net.
