The three fundamental equations are:
V = 0.639 √fR
Where V is regime velocity in m/sec.
Af2 = 141.2 V5(2)
V = 10.8 R2/3 S1/3 ..(3)
Where S is the slope of water surface.
V = 0.639 √fR
Where V is regime velocity in m/sec.
Af2 = 141.2 V5(2)
V = 10.8 R2/3 S1/3 ..(3)
Where S is the slope of water surface.
