For flows that can be calculated by the equation:
q = 1/1000 x B x h x V
where : q = flow rate in l/sec
B = channel width in cm
h = head in cm
V = velocity in cm/sec
RATIOMETRIC CALCULATION, P4 = 1

For flows that can be calculated by the equation:
q = q
cal
x A/A
cal
x v/v
cal
where : q = flow rate
q
cal
= flow rate at maximum head
h = head
h
cal
= maximum head
v = velocity
v
cal
= velocity at maximum head
