ABSOLUTE CALCULATION, P4 = 0¤
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 = qcal x A/Acal x v/vcal
where : q = flow rate
qcal = flow rate at maximum head h = head
hcal = maximum head v = velocity
vcal = velocity at maximum head
